Lee Ritenour's Rhythm Sessions is, in a roundabout way, a companion album to 2010's Six String Theory. For that record, he sought out a slew of guitar greats to celebrate their joint love for the instrument. Here, Ritenour assembles another top-flight cast for a set of tunes that range from fusion to pop, from contemporary jazz to post-bop and more. "The Village" places the guitarist with George Duke, Stanley Clarke, drummer Dave Weckl, and percussionist Munyungo Jackson. The fusion groove is nocturnal, slippery, even bluesy. Kurt Elling joins Dave Grusin, Nathan East, and Will Kennedy for an elegant reading of Nick Drake's "River Man." This utterly unique recording in the contemporary jazz genre is a fine showcase for his skills as a bandleader.
