ILLENIUM and Marshmello have spent years occupying different corners of the same melodic electronic universe, repeatedly crossing paths without ever fully converting that connection into an original release. With “Close My Eyes”, featuring SACHA, that gap finally disappears.
Released on September 9 through Marshmello’s Joytime Collective, the track represents the first original collaboration between the two producers, arriving nearly a decade after ILLENIUM remixed Marshmello and Khalid’s “Silence.”
Rather than attempting to turn the occasion into an oversized collision of festival drops, “Close My Eyes” takes a noticeably more restrained route. Airy guitars, SACHA’s intimate vocal performance and a melodic future-bass structure create a record built around emotional release rather than sheer impact, allowing the characteristics associated with both producers to overlap without either one completely dominating the production.
The result feels familiar without becoming purely nostalgic.
There are clear traces of the emotional melodic bass that helped define ILLENIUM’s rise, while Marshmello’s instinct for accessible songwriting and polished pop structures keeps the production direct. At the centre of everything is SACHA, whose vocal gives the collaboration the vulnerability necessary to prevent the instrumental from becoming simply another exercise in melodic EDM.
For two artists whose names have been associated with massive stages for years, “Close My Eyes” works precisely because it does not constantly try to sound massive.

A Collaboration Nearly a Decade in the Making
On paper, an ILLENIUM and Marshmello collaboration feels so obvious that it is almost surprising it took this long to arrive.
Both producers emerged during a period when electronic music was increasingly moving beyond the rigid divide between festival EDM and pop songwriting, building audiences around records capable of carrying emotional vocals while still functioning on large stages.
Their history already crossed nearly a decade ago when ILLENIUM remixed Marshmello and Khalid’s “Silence,” but “Close My Eyes” is officially their first original collaboration.
That history inevitably creates expectations.
A collaboration between artists of this scale could easily have become an exercise in combining the most immediately recognizable parts of their catalogues: enormous supersaws, dramatic vocal builds and an oversized festival drop positioned as the obvious meeting point between both fanbases.
Instead, the production feels considerably less interested in proving who made which part.
That may initially make “Close My Eyes” feel surprisingly understated, but it is also what gives the record some of its personality. The collaboration functions through overlap rather than contrast, with both producers working inside a shared emotional space instead of constantly competing for attention.
“Close My Eyes”: Melodic Bass Without the Excess
The opening immediately establishes the softer character of the record.
Light guitar plucks create space around SACHA’s voice before the arrangement gradually begins to expand, avoiding the kind of aggressive introduction that might normally signal an upcoming festival drop. EDM.com similarly describes the track as moving from airy guitar textures into a future-bass drop built around brighter synth layers.
The transition is important because “Close My Eyes” never relies on one dramatic moment to justify itself.
Its production instead develops through gradual additions.
The guitars establish vulnerability, the vocal gives the record narrative direction and the electronic layers eventually widen the emotional scale without completely removing the intimacy established at the beginning.
Even when the drop arrives, the track remains melodic rather than aggressive.
Beatport lists the release at 106 BPM in G-flat major, categorizing it within Dance / Pop, a relatively moderate tempo that reinforces how far the record sits from the more explosive side of contemporary bass music.
There is weight in the production, but not aggression for its own sake, that distinction helps “Close My Eyes” feel more like a song than a festival tool.
SACHA Gives the Track Its Emotional Centre
The collaboration may carry two of electronic music’s biggest names, but SACHA is arguably the element that determines whether it works.
Her vocal performance remains controlled throughout, avoiding the exaggerated delivery that can sometimes make emotional EDM feel overly calculated.
Instead, the vocal reflects the central idea behind the song: retreating into dreams when reality becomes too difficult to confront.
The imagery surrounding darkness, distance, rain and sleep creates a sense of absence, with dreaming becoming the only place where the relationship at the centre of the record can continue.
That concept fits naturally into ILLENIUM’s musical world.
Much of his catalogue has been built around loss, longing and emotional release, often using the contrast between intimate vocal sections and expansive electronic drops to transform private emotion into something communal.
Here, however, SACHA prevents that structure from becoming too predictable.
The vocal does not simply exist to prepare the drop. It remains the emotional reference point even after the instrumental grows around it.
That makes the electronic production feel like an extension of the lyric rather than the destination toward which everything else is moving.
Where ILLENIUM and Marshmello’s Sounds Actually Meet
One of the more interesting aspects of “Close My Eyes” is how difficult it can be to separate the two producers.
ILLENIUM’s influence is easiest to recognize in the melodic bass structure and the emotional pacing of the arrangement, particularly in the way softer instrumental passages gradually expand into wider synth-driven moments.
Marshmello’s presence is less about the helmet-era future bass sound that originally established him and more about songwriting.
His ability to reduce electronic music into highly accessible melodic ideas has been central to much of his crossover success, and “Close My Eyes” benefits from that instinct.
Nothing feels unnecessarily complicated.
The chorus arrives clearly, the instrumental reinforces it and the central melodic idea remains easy to recognize after the track ends.
That simplicity could also divide listeners.
Early community reactions have already reflected slightly different expectations, with some listeners praising the melodic collaboration and SACHA’s vocals while others have described the production as more restrained than they expected from two artists with such recognizable identities.
But that restraint is arguably the point, a collaboration does not necessarily become more convincing by making both artists louder.
Sometimes the more interesting result comes when their differences begin to disappear.
From Ultra Miami to Red Rocks
“Close My Eyes” was already beginning to develop a live history before its official release.
The track first surfaced publicly during ILLENIUM’s headline performance at Ultra Music Festival Miami in March, when Marshmello joined him on the Mainstage for a surprise appearance. It returned months later during their back-to-back performance at Red Rocks in August, giving fans another preview before the September release.
That progression matters because the track sits naturally between the studio and festival sides of both artists.
Its quieter sections create enough emotional contrast to work within a longer set, while the melodic release provides the scale necessary for large venues without requiring the production to become significantly harder.
ILLENIUM himself had continued teasing the collaboration immediately before release, confirming “Close My Eyes” with Marshmello and SACHA for September 9 through his official channels.
By the time the studio version finally arrived, therefore, the song already carried memories of two of the environments most closely associated with contemporary American electronic music: the Ultra Mainstage and Red Rocks.
A Softer Kind of Festival Record
“Close My Eyes” also arrives during an interesting moment for both artists.
ILLENIUM has spent much of 2026 touring around his sixth studio album, ODYSSEY, including his large-scale Sphere residency in Las Vegas, while Marshmello continues to operate across festival appearances, club residencies and the broader pop-electronic world.
Against that level of scale, the relative softness of this collaboration becomes more noticeable.
Neither artist needs another track simply to prove that they can fill a festival stage.
That has already been established.
What becomes more valuable is finding different emotional functions for their music within those performances.
“Close My Eyes” can work as a release of tension rather than another escalation of it.
Inside a set dominated by drops, pyrotechnics and increasingly aggressive production, a melodic record capable of creating a collective vocal moment can often feel larger precisely because it temporarily reduces the intensity.
This is where the collaboration potentially has its strongest live future.
It may not be the hardest record either producer releases this year, but it does not need to be.
Its purpose is different.
Final Thoughts
The most obvious version of an ILLENIUM and Marshmello collaboration would probably have been bigger, louder and more immediately recognizable.
“Close My Eyes” chooses another direction.
Instead of treating the combination of two major electronic artists as an excuse for maximum impact, the track builds around vulnerability, melody and SACHA’s vocal performance, using the production to amplify an emotional idea rather than overwhelm it.
There are moments where listeners familiar with either producer may expect the arrangement to push further, particularly given the scale normally associated with their live shows.
But the restraint ultimately gives the collaboration its identity.
After nearly a decade of musical crossover without an original track together, ILLENIUM and Marshmello have not attempted to recreate the period that first connected their names.
They have produced something cleaner, softer and more mature.
And while “Close My Eyes” may initially appear to be a straightforward melodic bass collaboration, its strongest quality is the way it understands that emotional electronic music does not always need a bigger drop.
Sometimes closing your eyes is enough.
