Insomniac has revealed the full artist lineup for Countdown NYE 2026, and the 12th edition is going big by expanding back to a two-day format for the first time since 2023. The New Year’s Eve staple returns to NOS Event Center in San Bernardino from December 31, 2026 through January 1, 2027, with a bill that stretches across bass, house, techno, UK garage, and hard dance.
Topping the lineup are Alesso, DJ Diesel (Shaq), DJ Snake, Gordo, Marshmello, Subtronics, Tchami, and a collaborative set from S.Y.N, the trio project uniting SVDDEN DEATH, YVM3, and NIMDA. Rounding out the tastemaker acts are Flosstradamus, Loud Luxury, Oliver Heldens, R3HAB, and Seven Lions, giving the two-day run a genre-spanning main stage pull that should draw fans from across Southern California’s dance music scene.
For bass and UK garage heads, the lineup digs deep with AHEE, Chozen, Deathpact, Ecchi.mp4, Ghengar, GorillaT, Green Matter, HEYZ b2b TYNAN, HOL!, Jessica Audiffred, LYNY b2b Peekaboo, MADVKTM, NGHTMRE, Smoakland, Space Laces, Troyboi, and Zingara. The UK garage contingent specifically brings 33 Below, Arlo, borne, bushbaby, Jev, MESSIE, and SKILAH into the fold, reflecting the genre’s continued foothold on North American festival lineups.
House and Techno Get Their Own Corner
Underground heads aren’t left out either. Countdown’s house and techno booking includes Archie Hamilton, Blaise Bracic, Brandon, BUNT., DJ Guestlist, Esse, HILLS, Jaden Bojsen, James Hype, Joshwa, Kelland, KHROME, KLOUD, Lavern, Lucky, Matroda, MIJA b2b SIM0NE, Noise Mafia, Ranger Trucco, Rinzen, ROZ, Taiki Nulight, TOBEHONEST, TOKiMONSTA, Walker & Royce, and Wax Motif. Hard dance fans get their own lane too, with DOMINA, GRAVEDGR, and Sincera on the bill…
