Since their formation in Los Angeles in 1998, 30 Seconds To Mars has searched for a perfect lineup. Jared and Shannon Leto started the band on their own as a family musical project with Jared providing guitar, keyboards, vocals, and lyrics and Shannon playing drums. Jared also has a significant and prolific acting career.
Shortly after forming, a bassist was added in the form of Matt Wachter who played with the band until 2007. The first two guitarists added to 30 Seconds To Mars, Kevin Drake and Solon Bixler, quit shortly after joining due to touring conflicts. Then along came a guitarist named Tomo Milievi who remains in the band to this day.
There are currently three official members of the band and two touring members. Jared Leto plays rhythm guitar and keyboards and provides the lead vocals and most of the songwriting. Shannon Leto plays drums and other percussion instruments. Tomo Milievi plays lead quitar, violin, and occasional keyboards. When on tour, Matt McJunkins plays bass guitar and Braxton Olita plays rhythm guitar, keyboards, and provides back-up vocals. Previous touring members include Kevin Drake on rhythm guitar from 2001-2002 and Tim Kelleher on bass guitar and keyboards from 2007-2010.
