In an unusual move for an established country singer, Brad Paisley's PLAY is a primarily instrumental album that puts its focus entirely on Paisley's underrated guitar work. Far from being a traditional country album, or even a contemporary country-pop album, PLAY works in a wide variety of genres, including Les Paul-style jazz, ripping surf rock, old-fashioned electric Chicago blues, and metal-tinged rock & roll.Paisley also assembles quite a list of guest stars: a re-recording of an early hit features a guest appearance by the actor Andy Griffith, while the Bakersfield country rocker "Come On In" features the late Buck Owens and a bluesy take on "Let the Good Times Roll" welcomes B.B. King. Two vocal tracks, "Start A Band" and "More Than Just This Song," feature Keith Urban and Steve Warriner, respectively, while the epic "Cluster Pluck" is a tongue-in-cheek high-speed dash through the history of country guitar showcasing James Burton, Vince Gill, Albert Lee, and four other guitarists besides. PLAY is a detour, but a worthwhile one.
