It was sometime in the late ’80s or early ’90s when it became uncool to enjoy bands like Ambrosia, as hair-metal machismo and grungy aloofness crowded the earnest, sensitive, souls of the ’70s off the airwaves. But within the last few years, something shifted, and the influence of AM pop and soft rock has been permeating indie rock, with Mac DeMarco, Ariel Pink and Foxygen unapologetically riffing on the grooves of the past. Ambrosia’s biggest hits were slow jams like “Biggest Part of Me” and “How Much I Feel,” and while they function as time capsules, their funky basslines, falsetto crooning and surprise sax solos have come back around to sounding contemporary again. It makes you wanna lounge on a shag carpet with a snifter of brandy.
