Thirty Seconds To Mars was co-founded by siblings Jared and Shannon Leto almost 15 years ago. Jared is now as equally well known for his on-screen work (movies like "Requiem for a Dream" and "Panic Room") as he is as lead singer for the band, a post-grunge rock group that is sometimes raucous, sometimes aggressive, and often reflective. The commercial floodgates seemed to open up after the release of "A Beautiful Lie," an album that broadened the group's sound to incorporate elements from the metal and ‘screamo' genres, among others.
