When it was released a few weeks ago, the first volume of Ivan Smagghe and Vladimir Ivkovic's two-part IDMEMO: A Future of Nostalgia compilation delivered a killer collection of largely forgotten or overlooked gems from the Artificial Intelligence-era of electronica and ambient techno. The second installment is equally as inspired, with highlights including the ever-changing, acid-flecked exoticism of the Black Dog's 'Psyil Cosyin', Autechre's haunting, 12-minute remix of Seefeel's 'Spangle', the Tangerine Dream-does-ambient trip that is Beautyon's 'To Swing Pil', and the stately beauty of Beaumant Hannant's 'Utuba (Reprised Version)'. Look out also for a largely unknown - and pleasingly melodious - remix of Soft Ballet by Richard D James under his infrequently used Polygon Window pseudonym.
