The trio recorded two EPs togethers, and played hundreds of gigs on their native Isle of Man before moving to London to live with Knowles's manager, Bob Miller (Corinne Bailey Rae, Christine Collister).

In 2007, with a spot secured at the SXSW Festival in Texas, Knowles and Doyle recruited former schoolmate Adam Jones to replace Jamie on bass.

On 27 January 2009, a letter was posted on Back Door Slam's website, announcing that the band had "broken up" and its members were pursuing different musical endeavors.

He then recorded a new album, Coming Up For Air, with Peter Frampton as co-Producer, (and also adding guitar, backing vocals & co-writing two songs), along with Benmont Tench (keys), Mauricio Fritz Lewak (drums) and Kevin McCormick (bass), which was released in June 2009.

He is now on the road as Davy Knowles and Back Door Slam, with PK (bass), Steven Barci (drums) and Ty Bailie (keys).
