Caravan is the first single from Canadian rock band Rush's 20th studio album, Clockwork Angels. It was released to radio stations and saw digital release on June 1, 2010 (a full two years before the album's proper release), on CD via mail order later that month, and as a 7" vinyl record for Record Store Day 2011, with a limited printing of 3000 units. The B-side is an additional studio track titled "BU2B", which stands for the lyric "brought up to believe". Both songs were recorded April 13, 2010, at Blackbird Studios in Nashville with producer Nick Raskulinecz with mixing and engineering done by Richard Chycki at the Sound Kitchen in Franklin, Tennessee. The songs were mastered by Ted Jensen at Sterling Sound in New York. Live appearances of both songs were first featured on Rush's Time Machine Tour.
