Any new 12" from Gerard Hanson is worthy of note, but there's something extra-exciting about this one. Fantastically, it sees him don the familiar Convextion alias - first used way by in 1995 - for the first time since 2007 for the latest 12" on Dynamo Dreesen's ever excellent Acido label. Boasting two long, slowly unfurling concoctions, Acido 22 is up there with his greatest work (and that's saying something). Thrillingly, it eschews the deep, spacey electro sound with which he made his name, instead turning to beat-less ambience; kind of Convextion does Pete Namlook, if you will. Both tracks are suitably sublime, with stretched-out chords, classical-style melodic movements, and memorable tunes that develop organically over the course of 11 or 12 minutes. Making great ambient music is hard, but Hanson knows exactly what he's doing.
