Nashville-based noise-pysch duo JEFF the Brotherhood rolled into Warner Bros. Studios in Burbank, Calif., yesterday (Nov. 15) for a performance on 'Conan,' and their ranks swelled to three as Jimmy Vivino of house band the Basic Cable Band sat in on flute for a fierce version of 'Staring at the Wall.' "That was killer," raved host Conan O'Brien at the conclusion of the mayhem. Indeed, it was, Conan. Indeed, it was.

JEFF the Brotherhood are in the midst of a North American tour that touches down in Cincinnati tonight and will keep them on the road through a Nov. 28 gig in Boston. Check out their complete itinerary here.
