Voltage Drop is a recurring industrial music dance party: Think dark synths, pulsing beats, and an eerie ambiance that creeps in like a veil of smoke. You can expect this sort of vibe at the latest edition of the event at The Legionnaire, with live electronic sets by Maya Songbird, an Oakland experimental pop singer and producer; San Francisco industrial DJ and producer NINE; and Chatty Mandril, the alter ego of Zachary James Watkins of the Oakland noise outfit Black Spirituals. Voltage Drop resident DJs Bonus Beast, Malo, and Kozi will be spinning, as well. Songbird’s set is definitely one to look forward to. While her music has industrial and electroclash undertones, it will be interesting to get to know the goth side of the sunshine-y disco pop songstress.
