‘We Are the 21st Century Ambassadors of Peace & Magic’ is a precocious and cocksure joyride across California psychedelia with a burning, bursting punk rock engine. In the same year as Scott McKenzie the singer of “San Francisco (Be Sure To Wear Flowers In Your Hair)” leaves this mortal coil, Foxygen delivers unto us the dandy Glockenspiel-packing “San Francisco,” which both circumvents and dissects McKenzie’s tune and its many cousins of the era. “I left my love in San Francisco/(That’s okay, I was bored anyway)/I left my love in a field/(That’s okay, I was born in LA)” goes the lovely call-and-response chorus, slamming together the archetypal flower children of the 60s and the archetypal ADHD vapidity of our recent generations. Another highlight, “Shuggie,” manages to fit all the light bounce of the song’s namesake and the climbing choruses of ELO into it’s 3 minutes while still filling the tune with imagery of “rhinoceros-shaped earrings” and haunted parlors. Every nook and cranny of the record is loaded with their unflappable, brazen personalities. Foxygen takes “swagger,” that as-of-late misused adjective, back once and for all. It’s flipping pyramids old and new upside down — from the miracle demo hand-off to their Richard Pryor-as-Jagger live shows to their singular idiosyncratic vision of rock n’ roll.
