Given the expansive nature of Terry Farley’s first celebration of early and classic house, 2013’s five-disc Acid Rain, you’d think he’d be running out of choices for this second, similarly epic selection. In fact, Acid Thunder is, if anything, a more pleasingly deep and in-depth collection. Whereas that first installment was heavy on relatively well-known classics, this follow-up digs deeper for inspiration. As a result, it’s packed with tracks that many house DJs simply won’t know, or have struggled to get hold of; not just stone cold classics such as Bobby Konders’ “Nervous Acid” or Hexx Complex’s “I Want You”, but genuinely overlooked material from the likes of Risque III, Peter Black and Jack James Rabbit. It’s something of a welcome history lesson, even for those with a good grasp of house music’s formative years.
