Guitarist Arthur Adams is primarily known as a session player, not to mention the bandleader at friend and collaborator B.B. King's Los Angeles blues club. On his first solo album in 20 years, Adams's guitar work is sure and deft, with the confidence that comes from years of experience. He's got a great voice, too, with an appealing smoothness that sounds fresh and contemporary, and that never lacks for expressiveness. The songwriting on Back on Track is mature, whether Adams is tackling the modern breakup (complete with lawyers and court settlements) in "Who Does She Think She Is" or exploring the complications of personal devotion in "Backup Man." He rocks out too, especially on the sensual "Honda Betty" (complete with horns) or the strong, driving "Jumpin' the Gun." If the music's not exactly mind-blowing, well, it isn't meant to be; its impact is felt in its unhurried thoughtfulness; Adams does ballads especially well. And, of course, there's the King guest spots on "Get You Next to Me" and "The Long Haul." --Genevieve Williams
