I watched Yacht Rock: A Documentary on Max this weekend, and I thought it would make for a good opportunity to reflect on this odd little subgenre that has become its own cottage industry over the last decade or so. The documentary focuses on a certain type of bouncy, smooth adult contemporary music popular in the late ‘70s and early ‘80s. This is the music that filled radio airwaves right after Motown’s classic era ended and right before MTV changed image-making in music forever.
