Insomniac Events is bringing the fantasy back to the Inland Empire this spring, as Beyond Wonderland announces its return to the NOS Events Center in San Bernardino with a genre-spanning lineup set for March 27–28.

Known for its surreal soundscapes, whimsical stage designs and immersive storytelling inspired by Alice in Wonderland, the two-day festival will once again transform the sprawling Inland Empire venue into a fully realized fantasy world.

A diverse mix of global dance music heavyweights and crowd favorites leads the 2026 lineup. Headliners include Tiësto, Deorro, Gareth Emery, Holy Priest, and Matroda. The bill also features major names, including Zedd, Alison Wonderland, Alok, Lil Texas,  SLANDER, Benny Benassi, Steve Angello, and Troyboi. Adding to the excitement, genre-blurring fan favorite GRiZ will make a highly anticipated return to Southern California following his 2023 hiatus announcement.

Spanning nearly every corner of electronic music, the lineup offers something for fans of bass, house, trance, techno and hard dance alike. Bass lovers can expect high-energy sets from acts like ATLiens, Black Tiger Sex Machine, Sullivan King, Dabin, and Trivecta, while house fans will be treated to performances from SIDEPIECE, OMNOM, Westend, Ranger Trucco, and it’s murph.
