Marshmello brings his signature helmet and high-energy production to XS Nightclub, where the dance floor sits just steps from Encore's pool and the room's curved, body-inspired architecture wraps around a serious sound system built for bass. Expect the kind of set that swings between euphoric drops, festival-sized anthems, and the occasional surprise mashup, all synced with the venue's light rigs and pyrotechnic flourishes that XS is known for.

The crowd here tends to be a mix of dedicated fans who know every track and Vegas nightlife regulars just looking for a big night out, so the energy stays loose and celebratory from the first note. Between the poolside patio for catching your breath and the packed main room for losing yourself in the music, XS gives Marshmello's blend of dance-pop and EDM plenty of room to breathe.
