Icelandic producer Yagya (AKA reclusive producer Aoalsteinn Guomundsson) doesn't release very much, with four studio albums and a lone single the sum of 12 years productivity. However, what he does release is usually top notch. Sleepygirls, his fifth album and first for Delsin, is predictably good, delivering warm, sensual, melodious, dub-inflected techno and undulating, ultra-deep house. Grooves shuffle, electronics drift between speakers, melodies bubble and chords float off into the ether. It's the kind of album to stick on while the sun's coming up, or as you're easing yourself into the day following a heavy session the night before. Any many ways it's as sleepy as the title suggests, but in the most beguiling way.
