Following up on the meeting of the progressive-jazz minds that took place on Pat Metheny and Brad Mehldau's mostly-duets album METHENY/MEHLDAU, the forward-looking pair expand their partnership to include a rhythm section on most of the songs. In this format, Metheny and Mehldau bring out the best in each other; simultaneously providing a framework for gorgeously melodic lines and egging one another on to the outskirts of improvisation. 　　Though the guitarist and pianist are of different generations, it's this combination of beauty and bravery that gives them their common ground. On "Silent Movie," for example, they indulge in a lambent feel, slowly unfurling lines of elegance and grace. Meanwhile, the quirky harmonies and free time they get into with "Santa Cruz Slacker," among others, reminds one of why both men remain leading lights of the post-bop world. 　　Pat Metheny/Brad Mehldau: Pat Metheny; Larry Grenadier (bass instrument); Jeff Ballard , Brad Mehldau. 　　Personnel: Pat Metheny (guitar, acoustic guitar, guitar synthesizer); Brad Mehldau (piano); Jeff Ballard (drums). 　　Audio Mixers: Pete Karam; Rob Eaton. 　　Recording information: Right Track Recording, New York, NY (12/2005).
