penseur wrote about Buddy Guy's rendition of Jimi Hendrix's Red House. Red House is an old blues standard that a million people cover, so Guy wasn't covering Hendrix he was just playing Red House.
I don't mean to nitpick but it's frustrating when I see things like "Clapton's I Shot the Sheriff" or "Aerosmith's Train Kept A Rollin". Covering blues tracks is a fundamental, and great, part of rock and roll, but the songs should be remembered for what they are, not some mega-bands rendition of them. Led Zeppelin's first album was almost entirely blues covers and it was awesome. Those guys constantly give credit to the great American blues legends. Without them there is no Led Zeppelin.
