Trapez Records boss Riley R. Reinhold is one of the best-connected DJs in the technosphere. That fact, plus his unerring ear for killer choons, makes his mix CDs overflowing banquets for 4/4 aficionados. Selection 5 maintains the tradition, as Triple R cherry-picks quality jewels from an international roster of elite producers (Jeff Samuel, Alex Under, N™ze) and dazzling newcomers (Rico Püstel, SLG, Sandiego). The Selection series generally nixes rowdy anthems in favor of headier, mid-tempo, boom-tsss fare and inventive textural quirks. Nevertheless, these 20 tracks will definitely generate serious body heat. Add another “R” to Riley’s moniker-reliable.
