"Brothers Ali and Basti Schwarz have been making music together as Tiefschwarz for close to 20 years. The partnership began with disco-flavoured deep house throughout the late '90s and early '00s, but has since moved into tech and electro house territory. Tiefschwarz's relationship with Watergate stretches back more than a decade, having appeared at the Berlin club regularly since it opened. Left will be the second album on Watergate's label arm, following Ruede Hagelstein's debut solo full-length, which comes out later this month. Tiefschwarz's effort comprises 13 tracks, with guest vocals coming from Khan, Mama and Emily Karpel." - Resident Advisor
