Mains Ignition started off as a three-piece outfit in the late 90s formed by Justin Anderson (singing, synths, sound effects, melodica, kazoo, etc), Paul Harrison (synths and sound effects) and Dave Rabjohns (synths and sound effects).

The three later took on two more members: Adam Ficek (drums, synths and percussion) & Lester Jones (4) (bass and sound effects) to become a five-piece.
