The band's new EP, Mo Voodoo, could win Mule some converts, mostly because the band keeps things concise. The addition of keyboardist Danny Louis to the power-trio lineup also helps. Louis forces his bandmates -- rounded out by drummer Matt Abts and bassist Andy Hess -- to concentrate on the songs, letting "I'll Be the One" breathe and giving a cover of David Grey's "My Oh My" a bit of grit without making it feel dusty. At the Scene Pavillion on Thursday, those songs will surely be extended, and for at least half the jam-band nation, that'll go down like iced tea with mint -- super-southern and flavored just right.
