1970 classic Blue Note album from Brother Jack Mcduff, exploring funky spacy soundscapes. Moon Rappin’ is a fairly typical album of its time, boasting wah-wah guitars, flutes, spacious reverb, long bluesy vamps, orchestras, and disembodied backing vocals, but it also stands out from the pack in how it offers some excellent improvisations (including a rare piano spotlight on the title track) and unpredictable moments, like the stuttering organ and nearly free interludes on “Made in Sweden”.
