Darwin Chamber is a veteran of the prog game, and now that sound is very much back en vogue, it's no wonder new generations are falling for the American's sounds. Back in March, he dropped this EP which was inspired by a San Fran acid trip, and it became an instant classic that meant the initial translucent yellow vinyl edition, limited to 303 copies, soon sold out. Now it reappears on black wax and obviously it still bangs. 'The Acid Test (DJ Spun mix)' is a heavy, raw jam with plenty of trippy details, warped pads and vocals that come and go so subtly you can't really be sure they're there. 'Never Coming Down' is a deep and dark workout with cold analogue hits and paranoid vocals, then '25th Century Acid Cat' is a little brighter with its synths but no less of a mind-fuck. 'Get Down' is gurgling, coruscated, sleazy and mid-tempo acid techno for the freaks. Brilliant.
