Best Supergroup: Puss N Boots
Norah Jones, Catherine Popper and Sasha Dobson – together, Puss N Boots – are all extremely talented multi-instrumentalists, but together their sound is pared down, with the emphasis on harmonies. "This is one of the first songs we ever got together on," said Jones, before easing into a gorgeous version of the Rodney Crowell (and more famously, Johnny Cash) tune "Bull Rider." Most excitingly, Mavis Staples was a surprise guest, helping on an achingly gorgeous cover of the Band's "Twilight." C.D.
