Classic weirdo country-soul-rock musician Jim Dickinson has passed on. To get a full appreciation of the man's contributions check out Robert Gordon's awesome book It Came From Memphis. Short version: He played piano on the Rolling Stones' "Wild Horses", and produced Big Star, the Replacements and Mudhoney.

UPDATE: Here's a massive, but no doubt incomplete, list of Dickinson's credits. The dude played with everyone from Aretha Franklin to Primal Scream.
