Since 2007, the band has been composed of actor Jared Leto (lead vocals, rhythm guitar, songwriter), Shannon Leto (drums, percussion) and Tomo Miličević (lead guitar, keyboards).

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 two extended plays – AOL Sessions Undercover (2007) and To the Edge of the Earth (2008).

A Beautiful Lie (2005–2008) :

Their second album, A Beautiful Lie, was released on August 30, 2005. Because the album was leaked five months before its release, the band decided to include two bonus tracks: "Battle of One" (an original song that was also set to be the album's title track when it was first announced) and "Hunter" (a cover of the Björk song). To further promote the album, the band also enclosed "golden tickets" in 12 copies, which granted their owners access to any 30 Seconds to Mars concert free of charge, along with backstage access.

On August 31, 2006, the band won the MTV2 Award for "The Kill" at the MTV Video Music Awards, one of their two nominations. The second nomination was for Best Rock Video; however, they lost to AFI's "Miss Murder". In the video, members of the band reenact scenes from The Shining. A Beautiful Lie was certified platinum by the RIAA in January for distribution of over one million albums.[6]

In 2006, while on the MTVu $2 Bill Tour, the band did a signing with Music Saves Lives, drawing people to the importance of the non-profit.

In October, the band began their "Welcome to the Universe" tour, sponsored by MTV2 and were supported by Head Automatica, The Receiving End of Sirens, Cobra Starship, Rock Kills Kid, and several other bands including Street Drum Corps. The tour was "environmentally sound" according to a 2006 interview with then-bassist Matt Wachter. "Jared and Shannon put together this thing called Environmentour which is illustrating ways—alternatives—to kind of clean up some of the mess we leave behind. We fueled the bus with vegetable oil," he explains.[7] On November 20, MTV2 premiered the video for "From Yesterday"; the video is the first American rock video ever shot in its entirety in the People's Republic of China.[8] The music video is loosely based on the film The Last Emperor.

On April 29, 2007, the band performed at the Australian MTV Australia Video Music Awards, where they were nominated for three awards, winning "Best Rock Video" and "Video of the Year" for "The Kill".

As of Spring 2007, the band is supporting The Used as a part of the "Taste of Chaos" tour and have scheduled a string of dates in Europe supporting Linkin Park. They are also scheduled to play Roskilde, Rock am Ring, Pinkpop, Give It A Name Festival and Download. 30 Seconds to Mars were one of the hosts for the MTV Europe Music Awards 2008. While on the 2007 Taste of Chaos the band also did an interview with Music Saves Lives.

On March 21, 2008, 30 Seconds to Mars performed at 'My Coke Fest' in South Africa, which saw the band back on South African soil since the inception and recording of A Beautiful Lie. At a Press Conference Leto described the experience as deeply personal, with the added hope that some new material may see the light of day on African Soil. The band played to a sold-out crowd in Johannesburg and Cape Town.

On December 11, 2009, according to AOL Radio Blog, with votes from listeners of the site's Alternative Radio station, the Top Alternative Song of the Decade of the 2000s was 30 Seconds To Mars' hit The Kill from 2006, which had major success, along with the album which the single appears, A Beautiful Lie.
