Best Covers

Three come to mind,

Smokestack Lightin' with The Yardbirds covering Howlin' Wolf.  Burnett even said it was the best version of his song.

Tje Allman Brothers Band covering Taj Majal's version of Statesboro Blues, which became their signature tune during Duane's leadership of the band.  Tah dis not write the song, but listen to his version and you can see where they got theirs.

Finally, Dolly Parton covering everybody, aometimes with the original artist on her new rock album. 

The entire Playing for Change series on YouTube. Amazing covers of many songs including The Weight, Gimme Shelter, Ripple, Doctor My Eyes, When the Levee Breaks, Soulshine, Higher Ground, Stir It Up, and others.

Teagan and Sarah covering Dancing In The Dark is kind of cute.

Check out the documentary "Echo In The Canyon"

Hosted by Jakob Dylan with a great group of artists. They cover the "California Sound" of the mid to late sixties. The associated album is fantastic!

@ezwind +1 to Playing for Change series--The Weight being the best of it

Not sure if Gregg Allman's "Midnight Rider" from Laid Back counts as a cover but maybe since we're stretching the rules a little?

Always like Linda Rondstadt's cover of Willin", esp the Live from Atlanta version
