Yes, it's time for sophisticated jazz fusion with legends Jaco, Shorter and Zawinul and marvellous Latin rhythm and percussion from the other two before Peter Erskine joined. This LP and the previous, Black Market, are wonderful examples of mid 70s jazz fusion from people who have been through the Miles Davis school of improv, but decided to rehearse the tunes a little longer ready to rock out on stage to the screaming college sophisti-cats. Jaco’s bass is great, Wayne’s sax is lyrical and Zawinul’s melodies and arrangements are hits even when his choice of synth sounds are poor. Great drumming and percussion as well. Mostly superb (who doesn't love Birdland?), but you really need to listen to the extended funk rock live version of Teen Town found on concert album "8.30" because it shows exactly why Weather Report were THE rockstars of jazz fusion.
