IO Echo vocalist, IO (a.k.a. Joanna Gikas), is the driving force behind the band. She composed a majority of the songs that comprise its eponymous debut. Originally from Washington, D.C., IO came to Los Angeles to form IO Echo. The band’s name is derived from the Greek translation of her name, Ioanna. She simply chose Echo because it rhymed with IO. From June 2009.
