Ben Deignan The Atlanta native looks and at times sounds like music industry giant John Mayer with a bluesy, soulful voice, and a pension for a catchy blues hook to reel in the potential listener who wants to groove. Deignan has a self-titled EP out full of easy-on-the-ears tunes often about the ins and outs of relationships. He and his band are currently a finalist in Hard Rock Cafe's version of "Battle of the Bands" competition, which culminates with the winner opening for the likes of Stevie Wonder and Paul McCartney at a Hyde Park show in London on June 25. $7, Double Door Inn, www.doubledoorinn.com.
