Now that you ask, the name Rifftides was inspired by a 1945 Coleman Hawkins piece, “Rifftide.” The tune was part of the celebrated 1945 Hollywood Stampede session that included trumpeter Howard McGhee, one of the bebop kiddies Hawk nurtured. Thelonious Monk had played with Hawkins the year before. Monk later recorded the tune and called it “Hackensack.” Either way, it’s based on the harmonic structure of “Oh, Lady Be Good,” but copyright law doesn’t cover chord changes, and George Gershwin’s estate earned no royalties. Nor can titles be copyrighted, so I stole Hawkins’s and pluralized it.
