Rainy Day is an album by jazz trombonist and arranger Kai Winding featuring vocal group, The Prevailing Winds, recorded in late 1964 and early 1965 for the Verve label.

[1][2][3] The Allmusic review by Tony Wilds said "Whether Rainy Day is best saved for one remains in doubt, but at least the concept balances the many mod albums selling nothing but "Madison Avenue"'s sweetness-and-light".
