A longtime fixture on the DC music scene, Olivia Mancini now splits her time between here and Brooklyn. She and her Mates will release a new singles collection called Interregnum on August 20th, surely rolling up some of the tracks posted to Olivia’s Bandcamp recently. You’ve got a great opportunity to see Olivia & The Mates this Friday night at Iota in Clarendon, with supporting acts Nine Times Blue from Atlanta and Nashville’s Luella And The Sun. And if that doesn’t work for you, she’s quite excited to open for Matthew Sweet at the Birchmere on August 23rd. Olivia’s newest music video, a scratchy vintage accompaniment for Ruby, Baby, is a song that parallels Dion’s 1963 hit single of the same name.
