Hootie & the Blowfish frontman Darius Rucker brings his forceful pipes to bear on songs packed with honest emotion and seemingly effortless charm. One moment he’s teaming up with Sheryl Crow or Mallary Hope for a couple of heart-stirring ballads (“Love Without You” and “I Will Love You Still,” respectively), the next he’s kicking up some country funk on the party-starter “Radio” or nodding to his former life with the roots-rocking slam-bang of “Heartbreak Road.”
