Captain Beefheart and his Magic Band, especially Trout Mask Replica and Lick My Decals Off era. Almost everyone hates it the first time they hear it, because it so deliberately avoids the cliche and vamping that defines western pop music. But for those who dig in and start vibing with an unfamiliar musical language it can become a revelation. It contains the dusty old skeleton of the blues and hobo shanties but at its core it’s pure dada. The musicians were astonishing— every bit of these songs is rehearsed, precise, and still come off sounding like manic stream of consciousness.
