by Scott Yanow The first recording by the Pat Metheny Group features the innovative guitarist along with keyboardist Lyle Mays, bassist Mark Egan, and drummer Dan Gottlieb. The music is quite distinctive, floating rather than swinging, electric but not rockish, and full of folkish melodies. The best known of these six Metheny-Mays originals are "Phase Dance" and "Jaco." This music grows in interest with each listen.
