This is War is the violent, explosive and all-round spectacular third studio album by American alternative rock band Thirty Seconds to Mars. Continuing the forward-push hard rock sounds of 30 Seconds to Mars and A Beautiful Lie, this album introduced frontman Jared Leto’s now famous Wall-esque leadership of the Echelon, the band’s cult following. This factors in choirs and mass choruses, and lyrics that called the Echelon into social warfare. The album has sold nearly four million copies worldwide, and it propelled the band through 300 shows in just two years (currently the longest run of live shows on a single album cycle). Ironically, Thirty Seconds to Mars recorded their aptly titled album while embroiled in a $30 million dollar lawsuit from label EMI. This led to an exposure of the music industry in their documentary, Artifact. The movie premiered at the 2012 Toronto International Film Festival and won the BlackBerry People’s Choice Documentary Award.
