'Invitation' was the third album by Jaco Pastorius, originally released in 1983 while the bassist was a member of Weather Report. This is a live album recorded at various venues during a tour of Japan, featuring his 'Word of Mouth' big band. While his debut album 'Jaco Pastorius' showcased his eclectic and impressive skills on the electric bass, both 'Invitation' and his previous album, 'Word of Mouth' focused more on his ability to arrange for a larger band. This album features mostly numbers written by other artists. The exceptions are 'Continuum', from his debut album, and 'Liberty City', from 'Word of Mouth', as well as 'Reza', an original number book-ending his version of John Coltrane's 'Giant Steps'. The band's all-star cast included Randy Brecker, Bobby Mintzer, Toots Thielemans, Peter Erskine, Othello Molineaux and Don Alias.
