(MUSIC) America's fabbest brother-sister rock combo traffics in baroque melodic flourishes, irresistible hooks, and more tantalizing surprises per track than most groups muster per album. Even if the new, grandma-featuring Rehearsing My Choir doesn't reach the vertiginous art-pop heights of their previous work, Fiery Furnaces still radiate an intense heat live.
