Created in 1998 by Jared Leto and his brother, Shannon, 30 Seconds to Mars began as a small family project. Things began to speed up quickly, and Matt Wachter later joined the band as bassist and keyboard player. After working with small revolving door of guitarists (as the band's first two guitarists, Kevin Drake and Solon Bixler, left the band due to issues primarily related to touring), the three auditioned Tomo Miličević to round out the band's roster.
