You're not a Return to Forever fan until you've taken in the band's disco-era jams, like the sultry, boisterous “The Musician”, and you're not a Corea aficionado unless you've sampled his orchestral pieces like “The Continents”—a concerto merging florid Leonard Bernstein–style harmony with swinging breakdowns. Corea is a restless experimenter, which also comes out on his jazz-duo sessions with Herbie Hancock.
