Thirty Seconds to Mars

30 Seconds to Mars is an American rock band from Los Angeles, formed in 1998. Since 2007, the band has consisted of actor Jared Leto (lead vocals, rhythm guitar, songwriter), Shannon Leto (drums, percussion) and Tomo Tomo Miličević (lead guitar, keyboards). Following the departure of Matt Wachter (now of Angels & Airwaves) in 2007, Tim Kelleher became the bassist for the group, performing live only with both Jared and Tomo Miličević recording bass for studio recordings, while Braxton Olita (keyboards) was added to the touring lineup in 2009. Previously, the group also featured guitarists Solon Bixler (now of Great Northern) and Kevin Drake.
To date, 30 Seconds to Mars have released three studio albums - 30 Seconds to Mars (2002), A Beautiful Lie (2005), This Is War (2009) and three extended plays - AOL Sessions Undercover (2007), To the Edge of the Earth (2008), and MTV Unplugged: 30 Seconds to Mars (2011).
30 Seconds to Mars' music has been associated mostly with progressive rock, progressive metal and post-grunge, but they have also included screamo, emo, space rock, synth rock and post-hardcore into their music. They have been compared to Pink Floyd (who were an influence on their work) and Tool because of their use of philosophical and spiritual lyrics, concept albums and their use of experimental music.
