Now that we’re marking the 40th anniversary of the Beach Boys’ landmark album Pet Sounds, it was probably inevitable that someone would mash-up the 1966 disc with its most noteworthy response, the Beatles’ Sgt. Pepper’s Lonely Hearts Club Band. Clayton Counts has taken on the task, cross-breeding the songs track by track in order, and he’s posted the resulting epic of Danger Mousery, Sgt. Petsounds, at his blog. It’s not really a straight mash-up, as Counts doesn’t really try to align the clashing rhythms or keys. The result has an abstract, free-jazz quality that’s both illuminating (in the way it honors the sonic experimentation of the originals) and headache-inducing. Anyway, it’s worth a listen.
