No matter how hard you try, you're probably not going to find much information on '70s New Zealand band Chook. Their "Cold Feet" single was thought to be long lost, but Permanent Records and RidingEasy Records have managed to dredge up Chook for their new compilation, Brown Acid: The Third Trip.

Chook is a great representation of what the series does best: exposing long-forgotten proto-metal that never quite got its due. "Cold Feet" is the kind of prize you'd find after a long day of crate-digging (if you happened to find yourself transported back in time to the '70s). The song is a sonic high, heavy guitars playing contorting riffs while catchy yells stoke the fire. It's a great distillation of what the underground was capable of back in the day, and still feels as fresh and poignant now.
