Hey, it’s the 20th Anniversary half-speed master vinyl edition of the Smog classic, ‘Knock Knock’, by Smog. Placing this LP on your turntable, you find yourself drawn ever-deeper into the sound - and it’s not just the eternally-stunning co-production from Callahan and Jim O’Rourke, it’s the incredible focus brought by the half-speed mastering work done at Abbey Road, bringing out the highs, lows and even mids that OG fans of this album have taken for granted for too many years. The fresh fullness of the sound now stands as a tribute to the ol’ familiar Smog sensation of being somehow completely unfamiliar.
