Join us Friday September 12th for our classic festival afterparties - this time ArioVistus (Montréal - Berlin Records/Tragedie) returns on the decks to headline what promises to be a sold out show. He wil be accompanied by DASA and and.re, two well-renowned local DJs. Expect the usual Obisidian sound; dark grooves featuring a blend of House & Techno in a vast variety of shapes, this time adapted to a more mainstream crowd given Riverside's headliner : Tiesto. Put your black attire, shades & earplugs on; and LET'S RAVE.
