Although listeners often think about Jaco Pastorius‘ first solo album as 1976’s Jaco on Legendary, producer/keyboardist Paul Bley really offered Pastorius his very first main chance at professional taping two years earlier. Coincidentally entitled Jaco (initially entitled Pastorious/Metheny/Ditmas/ Bley), this spontaneous set is likewise considerable for being amongst guitar player Pat Metheny‘s first recordings; completing the quartet are Bley on electric piano and drummer Bruce Ditmas. The music includes 3 songs by Bley, five from Carla Bley, and “Blood” by Annette Peacock. Pastorius sounds rather powerful, however Metheny‘s tone is sort of unusual, extremely distorted, and not distinctive at this moment. The taping quality is a bit shaky throughout the electronic set, and the group does not quite live up to its prospective, but Pastorius programs that he was currently an ingenious player, making this an LP of historical interest.
