In the latest episode of the Sadmen's journey down a rock and roll highway that starts in 1970(ish) and ends in 1995(ish), the lads pull out the corduroys and the paisley shirts and head for the warm bath of psychedelic bewilderment that was 1972. Having encountered Jethro Tull's Aqualung some 68 episodes previously, and hashed out the whole 'is it a concept album, isn't it a concept album' debate, it was time to make the acquaintance of its successor - Thick As A Brick. There were many questions to be answered, but none of them was 'Is this a concept album?' because of that, friends, there is no doubt. The problem with the Enter Sadmen podcast is that when one of the boys goes a bit weird, the other two follow suit. It's like Pavolv's dogs. Or something. Anyway, it doesn't matter. All you need to know is that getting on board with the 'out there' vibe were two more releases that are as curious as they are obscure. From Richard, a trip back to Canada to root out the self-titled debut by A Foot In Cold Water. From Steve, a slightly less arduous journey up the M1 to Northamptonfor Dark Round The Edges, the only release by a band called Dark, and one that will set you back a cool £35,000 to buy on vinyl today. We shit you not.
