Mersiv Rocks 444: Terraform, a deep dub and experimental bass music event headlined by Mersiv at Red Rocks Amphitheatre.
Mersiv returns to Red Rocks Amphitheatre on Friday, October 23, with Mersiv Rocks 444: Terraform. It's his fourth consecutive headline at the venue, and he's billing it as his most complete vision of the place yet. The night is built around two full sets—a Slowdown and a Throwdown—so you get both the deep, atmospheric side and the heavier, dancefloor side of his sound in one go.
This is part of the next phase of his live experience. In 2025, he debuted the 'audio sphere' listening experience, which speaks from the bottom up throughout the amphitheatre, and Terraform continues that evolution. Mersiv is a figurehead of deep dub and experimental bass, and he's worked with rappers like Juicy J along the way.
The support is a full run of bass acts. Know Good is a duo of cousins, Tanner and Sylas Morgan, who mix DJ sets with live drums, guitar, violin, and vocals. Jaenga headlined the Ogden Theater in early April. Phrva is known for flips of 'Lunch', 'Espresso', and 'Shabba', and for the six-track Genesis EP on Deadbeats. French artist Dr. Ushuu saw his track 'Camden Town' go viral and land him on the cover of Spotify's Dubstep Don playlist with support from DJ Snake. Bass producer Vyhara rounds out the bill, with tunes co-signed by Spotify.
