Background: Thirty Seconds to Mars (commonly stylized as 30 Seconds to Mars) is an American rock band from Los Angeles, California, formed in 1998. The band consists of Jared Leto (lead vocals, guitar, bass, keyboards), Shannon Leto (drums, percussion) and Tomo Milicevic (lead guitar, bass, violin, keyboards, other instruments). The band's debut album, 30 Seconds to Mars (2002), was produced by Bob Ezrin and released to positive reviews but only to limited commercial success. The band achieved worldwide fame with the release of their second album A Beautiful Lie (2005), which received multiple certifications all over the world, including platinum in the United States.
Context: Thirty Seconds to Mars took a break from touring in 2012 and spent most of the year recording their fourth album, entitled Love, Lust, Faith and Dreams. The album was produced by Jared Leto with previous collaborator Steve Lillywhite. Leto said that the band took a new direction with Love, Lust, Faith and Dreams. He explained that the album "is more than an evolution, it's a brand new beginning. Creatively, we've gone to an entirely new place, which is exciting, unexpected, and incredibly inspiring." In September 2012, Artifact, a documentary about the band's legal battle against the record label EMI and the making of This Is War, premiered at the Toronto International Film Festival and won the People's Choice Documentary Award. In February 2013, it was announced that "Up in the Air" would be the first single from the fourth album. In partnership with NASA, Thirty Seconds to Mars launched the first copy of "Up in the Air" aboard the Dragon spacecraft on SpaceX CRS-2. The mission was launched atop a Falcon 9 rocket on March 1, 2013, sending the first ever commercial copy of music into space. On March 18, 2013, the single premiered from the International Space Station, after a Q&A session with the band and Expedition 35 flight engineer Tom Marshburn, while Annise Parker, mayor of the city of Houston, proclaimed the Thirty Seconds to Mars Day. "Up in the Air" made its radio debut on March 18 and became commercially available for downloading the following day. The song reached number three on the US Alternative Songs chart and experienced success in international markets. Thirty Seconds to Mars released Love, Lust, Faith and Dreams on May 21, 2013, through Universal in the United States. The album received generally positive reviews and reached the top ten in more than fifteen countries, including the United Kingdom and the United States. The band began their Love, Lust, Faith and Dreams Tour in June, which included festival dates at Rock Werchter, Pinkpop, Rock in Rio, and Rock am Ring. The second single from the album, "Do or Die", achieved a level of play on modern rock radio, while "City of Angels", the third single, was released to rave reviews from critics and eventually reached number eight on the Alternative Songs chart in the US. At the 2013 MTV Video Music Awards, held on August 25, "Up in the Air" won the award for Best Rock Video. Thirty Seconds to Mars announced on April 25, 2014 that they have parted from Virgin Records after tumultuous years with the label, with Leto telling Billboard, "We're free and clear and excited about the future. It's the most wonderful place to be." In August 2014, the group embarked on a double-headline tour, dubbed the Carnivores Tour, with American rock band Linkin Park, visiting arenas and stadiums throughout North America. Thirty Seconds to Mars then launched a music festival called Camp Mars. The first edition took place in Malibu, California, in August 2015 and included a series of activities in a semi-rustic setting and several DJ sets. CANNOTANSWER
