Steve Harris formed the band to play in small venues, as opposed to the large arenas typically played by Iron Maiden, and as an outlet for shorter hard rock-oriented songs in which he can experiment with different bass guitar styles. The band also includes singer Richard Taylor, guitarists David Hawkins and Grahame Leslie, and drummer Simon Dawson.
The album British Lion, released in 2012, was marketed as a solo album by Harris with the other musicians described as his backing band. The album was voted Album of the Year by Paul Stenning for BraveWords.
