This reissue greatly enhances the fidelity of Jaco Pastorius, particularly in the bassist's famous, elusive tone, from lightly chorused, vocal-tenorlike glissandos on "Continuum" and the bell-like harmonics of "Portrait of Tracy" to his percussive, hand-drumlike rhythmic cycles underneath Peter Gordon's august French horn on "Oknokole Y Trompa." Even more stunning are the manner in which Jaco deploys a steel drum choir underneath Wayne Shorter on "Opus Pocus" and the ferocious Latin-inflected groove Jaco, Lenny White, and Don Alias conjure under Herbie Hancock on two takes--one unissued until now--of "(Used to Be a) Cha-Cha." Pat Metheny contributes an extraordinary set of liner notes to this set, putting Jaco's contributions to jazz and the bass in sharp perspective. Still, a spirit of innovation and discovery suffuses every note on Jaco Pastorius, and it is startling how modern and engaging this music remains. --Chip Stern
