Front Line Assembly (FLA) is a Canadian electro-industrial band formed by Bill Leeb in 1986 after leaving Skinny Puppy. FLA has developed its own sound incorporating elements of electronic body music and electro-industrial. The band's membership has rotated through the years, including Michael Balch, Rhys Fulber, and Chris Peterson, all of whom are associated with several other acts.

Electro-industrial is a music genre that emerged from industrial music in the early 1980s. While EBM has a minimal structure and clean production, electro-industrial tends to have a grittier, complex and layered sound with a more experimental approach. The style was pioneered by Skinny Puppy, Front Line Assembly, Numb, and other groups, either from Canada or the Benelux. In the early 1990s, the style spawned the dark electro genre, and in the mid-/late-1990s, the aggrotech offshoot. The fan base for the style is linked to the rivethead subculture.
