Weather Report’s best-selling album is also Jaco’s first as a co-leader. Here, Zawinul’s mega hit “Birdland” leads off the album, followed by Jaco’s lyrical fretless work on “A Remark You Made” and Jaco’s own “Teen Town” (with Jaco on bass and drums). Jaco was nominated for a Grammy (Best Jazz Soloist) for his work on this album.
