The Peak Oil favourite and long-anonymous producer breaks cover with two hours that run from post-punk and dub to vintage New York house. Mystery is a powerful force. What stays unknown stays enticing—negative space the listener fills in for themselves. Minimalists may be its largest constituency, and few have held the line as long as Topdown Dialectic. That changed with False LP A, which finally named him: Izaak Schlossman, a San Francisco photographer who spent years issuing untitled, identically timed tracks with no narrative attached. Coming out of the shadows hasn't cost the music its haze. Working in the Basic Channel lineage, Schlossman lays tracing paper over house and dub techno and pulls through the faintest outline—a bassline's shadow, the memory of a chord. Tracks surface the way bodies emerge in a steam room. He belongs to a North American underground that's been among dance music's most progressive forces this past decade—no surprise, then, that he credits Scott Zacharias of Detroit's No Way Back in the Q&A. This isn't quite the end of the mystery. Only the second Topdown Dialectic mix to surface, RA.1049 wipes the condensation from the glass just long enough for a look inside: it opens with a cut from German label Workshop before drifting from atmospheric post-punk and dubbed-out house into cosmic electro and, by the close, vintage New York house. It moves at an unhurried, chugging pace, but never mistakes restraint for stasis—each track quietly recalibrating until another contour comes into view.
