Though 33 was first conceived as a collaboration between the artists Billy Bultheel and Alexander Iezzi, it has since ballooned into a full band unit. Featuring the addition of CEM and Ivan Cheng, the group’s forthcoming release, Tripolar, is a dissonant and difficult-to-classify album. Using improvisation as a jumping-off point, Tripolar bobs and weaves around a variety of styles with a variety of collaborators—names include Astrid Sonne and Olan Monk—and is more the result of a madcap sense of play and possibility than any overarching conceptual or formal themes. The band will present their album live with a show at Berlin's Volksbühne on March 26th. Read our interview with 33, and listen to their new single "Worry Days" below.
