Ozma is an American rock band from Pasadena, California. The band's sound is a mix of new-wave–influenced power pop and contrapuntal Casiotone-driven melodies sustained by heavy guitar riffs. The complexity of Ozma's songs grew considerably during the band's initial nine-year history. After their split in 2004 they announced their reformation in early 2006.
Ozma was formed in 1995 by Ryen Slegr (vocals/guitar), Jose Galvez (guitar/vocals), Patrick Edwards (drums) and Daniel Brummel (vocals/bass), when Brummel was introduced to the others by Galvez, whom he had met on the internet while looking for a band to join. In 1996, the as-yet-unnamed band were joined by Katherine Kieckhefer on keyboards, before deciding on the name "Ozma" (taken from the L. Frank Baum books) in 1997, and in 1998 were joined by Star Wick, who replaced the departing Kieckhefer.
