Stockholm's Mackaper make psychedelic music built around the tinny drum beats and vintage tones of old Hammond organs. Originally the duo of Markus Hulthen and Per Nyström from the Concretes, the band has expanded into a six piece and mastered a sound that's equal parts Swedish prog, hypnotic motorik riffs, and wild bursts of free jazz. Highlights of the group's latest album, When All Is Sad and Dawn (out on Airwaves earlier this year), include pseudo-title track "Sad and Dawn," powered by the jazzy drumming of Simon Stålhamre and a circus-esque organ melody; the pastoral "Tindra," with its dewy mixture of organ, melodica, and french horn. "Tale of Tales" emphasizes swirling, gothic organ melody and wordless, ghostly female vocals to great effect. Remixes of "Tale of Tales" by Ultra El and Joxaren out on iTunes on april 26.
