German techno vet Timo Maas has been an active player in the scene for more than 30 years, having played his first club gig at age 17. Known for his unique collaborations and ability to cross and blend genres beyond the techno norm, Maas brings his experimental style to Brooklyn for another edition of Don't Be Leftout. Leftroom label boss—and, according to Seth Troxler, “the last great British DJ”—Matt Tolfrey tops the lineup, with support from Verboten resident Niki McNally.
