30 Seconds To Mars guitarist Tomo Milicevic has quit the band, according to Loudwire. The news came from Milicevic himself in a tweet that said, “I am no longer in 30 Seconds To Mars. I don’t really know how to explain in a note how I could have come to a decision like this, but please believe me when I say that this is the best thing for me in my life and also for the band.” Milicevic joined 30 Seconds To Mars in 2003 and has performed on all four of the band’s albums since then, starting with its 2005 sophomore effort A Beautiful Lie. 30 Seconds To Mars is currently in the midst of a lengthy North American tour, and at press time it was unclear how the band was going to proceed without its guitarist.
