Divided cleanly between an abstract studio side and an explosive live side recorded in Tokyo, this second Weather Report outing features the original core lineup of Joe Zawinul (keyboards), Wayne Shorter (saxophones), Miroslav Vitouš (bass), Eric Gravatt (drums), and Dom Um Romão (percussion). Tracks like "Unknown Soldiers" offer haunting, cinematic jazz, while the live segment showcases a band pushing jazz beyond traditional solo-plus-accompaniment dynamics into total collective expression. 2.
