Thirty Seconds to Mars

Thirty Seconds to Mars (commonly stylized as 30 Seconds to Mars) is an American rock band formed in Los Angeles, California, in 1998. The band consists of brothers Jared Leto (lead vocals, guitar, bass, keyboards) and Shannon Leto (drums, percussion), with various line-up changes throughout its history, most notably involving Tomo Miličević (lead guitar, bass, violin, keyboards, other instruments).

The band's debut album, 30 Seconds to Mars (2002), was produced by Bob Ezrin and released to positive reviews but only to limited commercial success relative. The band achieved worldwide fame with the release of its second album A Beautiful Lie (2005), which received multiple certifications all over the world. Its next release, This Is War (2009), showed a dramatic evolution in the band's musical style, as it incorporated experimental music as well as eclectic influences. The recording process of the album was marked by a legal dispute with record label EMI that eventually became the subject of the documentary film Artifact (2012). Thirty Seconds to Mars then moved to Universal Music and released the fourth album, Love, Lust, Faith and Dreams (2013), to critical and commercial success. It was followed by America (2018) and It's the End of the World but It's a Beautiful Day (2023), which both polarized critics upon release.

As of September 2014, the band had sold over 15 million albums worldwide. Thirty Seconds to Mars has consistently enjoyed sold out tours and numerous headlining festival slots. The band is noted for its energetic live performances and for fusing elements from a wide variety of genres, through its use of philosophical and spiritual lyrics, concept albums, and experimental music. Thirty Seconds to Mars has received several awards and accolades throughout its career, including a Guinness World Record, and has been included in the Kerrang! list of best artists of the 2000s.
