During this period Leto focused increasingly on his music career, working with producers Bob Ezrin and Brian Virtue on his band's debut album 30 Seconds to Mars, which was released on August 27, 2002, in the United States through Immortal and Virgin. It reached number 107 on the US Billboard 200 and number one on the US Top Heatseekers.[38] Upon its release, 30 Seconds to Mars was met with mostly positive reviews; music critic Megan O'Toole felt that the band managed to "carve out a unique niche for themselves in the rock realm."[39] The album was a slow-burning success, and eventually sold two million copies worldwide
