Side-project of Steve Harris.
Richard Taylor and Grahame Leslie were members of a band called British Lion, who approached Steve Harris in 1992 with a view to produce them. Steve liked their songs, and agreed to help, but the band imploded later on.
Richard Taylor started a new band with David Hawkins, and Steve joined in some of their writing sessions.
Eventually all four of them came together, and continued working as a band on the album that became British Lion.
