"Up in the Air" is a song recorded by American rock band Thirty Seconds to Mars, featured on their fourth studio album, Love, Lust, Faith and Dreams (2013). Written by lead vocalist Jared Leto, who also produced the song with Steve Lillywhite, "Up in the Air" is an introspective and passionate track reflecting upon human consciousness. It marked a departure from much of the band's previous work as it incorporates a more electronic-influenced sound as well as elements from new wave music.
