Ultra 2027 B2B Debuts: Marshmello B2B Subtronics, Boris Brejcha B2B Eric Prydz as Cirez D

Two back to back sets headline Ultra 2027 Phase 1: Marshmello B2B Subtronics makes its world debut, and Boris Brejcha B2B Eric Prydz as Cirez D hits the US.

Phase 1 posters are usually a wall of names. Ultra 2027 has two lines on it that are whole stories by themselves.

MARSHMELLO B2B SUBTRONICS, WORLD DEBUT

Marshmello is the biggest pop crossover name in dance music. Subtronics is the king of the heavy bass kids. On paper those crowds barely overlap.

That's exactly why this works. A world debut means nobody has a bootleg, nobody has a tracklist, nobody knows who takes which drop. The first time it happens, it happens at Bayfront Park, and everybody in that park knows they're seeing the only version of it.

The second one is for the heads. Boris Brejcha plays high tech minimal in a Joker mask and runs a set like a pilot. Eric Prydz as Cirez D is his dark techno side, the one American fans mostly get on records and phone videos from Europe.

Together, in the US, for the first time. The RESISTANCE crowd eats sets like this alive. Two perfectionists, one booth, no warm up act energy at all.

AND ONE MORE FIRST

Alison Wonderland B2B Tiffany Day is a festival debut, and it sits lower on the poster than it will sit in the Monday morning conversations. Remember that line when March comes.

We put both big debuts at the top of our Top 10 acts to see at Ultra 2027. The full Phase 1 lineup breakdown is live too. March 26 to 28 can't get here fast enough.
