30 Seconds to Mars is an American rock band formed in Los Angeles, California in 1998. Led by actor and musician Jared Leto alongside his brother Shannon Leto, the band is known for its cinematic, anthemic sound and elaborate live performances. Jared Leto is the primary creative force behind the band, writing virtually all lyrics and music, and serving as a producer on several albums. The band's self-written catalog places them firmly in the 'complete artist' tier despite their large mainstream following.

Data Insight

Jared Leto holds both lyricist and composer credit on every track across all six studio albums. The rest of the band — Shannon Leto on drums, Tomo Miličević on guitar — are performers without significant songwriting credit. This makes 30STM one of the rare major-label rock acts where creative authorship is concentrated entirely in the frontman.
