The band 30 seconds to Mars was pounded in 1998 by Jared Leto (born in 1971) and his elder brother Shannon (born in 1970). The group also featured guitarist Solon Bixler (now of Great Northern) and Kevin Drake (now of Polaroid Kiss). The next set of guitarist were Matt Wachter and Tomo Milicevic. The departure of Matt in 2007 forced Jared and Tomo to record bass for studio recordings and to find another bassist for live performances - Tim Kelleher. Braxton Olita (keyboards) was added to the touring lineup in 2009. The band has released 4 studio albums: "30 seconds to Mars" (2002), "A beautiful lie" (2005), "This is War" (2009) and "Love, lust, faith + dreams" (2013). Their "into the Wild Tour" broke touring records the band was giving live shows for 2 years all over the world. They performed 300 shows, the last one in December 7, 2011.
The long breaks between records being released were caused by the frontman's another passion - acting. The band even moved to Europe to record "A beautiful lie". A part of their last album "Love, lust, faith + dreams" was written in Łódź, Poland and it was recorded in India, of which influence you may hear in the song "Pyres of Varanasi".
Most of their videos were directed by Bartholomew Cubbins (a.k.a. Jared Leto).
