The pianist/composer Nils Frahm and his childhood friends Frederic Gmeiner and Sebastian Singwald recorded these songs in the 00s in Berlin; a decade later, they dusted off the tapes and edited their improv sessions into these loose-but-lean jams. Krautrocks muscular rhythms and dubbed-out guitars drive Ceramic People; Philip Glass influences the arpeggios of The Invention Mother. Vibraphones and incidental drums fuel the airy atmospheres of Capstan, while Chasing God Through Palmyra and Pink Flirt sink into ambient post-rock. The beats come back on Re:Turn! as Frahms keyboards meet hypnotic grooves.
