"Caravan" is the first single from Rush's new album “Clockwork Angel’. It was released to radio stations and saw digital release on June 1, 2010. The B-side is an additional studio track titled “BU2B”. Both songs were recorded with producer Nick Raskulinecz with mixing and engineering done by Richard Chycki in Sound Kitchen's Studio C. According to drummer Neil Peart’s latest personal essay, these two new songs are the initial parts of what he refers to as an “extended album-length story”
