Super Furry Animals are a Welsh rock band formed in Cardiff in 1993. For the duration of their professional career, the band consisted of Gruff Rhys, Huw Bunford, Guto Pryce, Cian Ciaran, Dafydd Ieuan. An earlier incarnation of the band featured actor Rhys Ifans on lead vocals.

Guerrilla is the third studio album by Welsh rock band Super Furry Animals. The record was released on 14 June 1999 by Creation Records and peaked at number 10 in the UK Albums Chart. Guerrilla was conceived as a commercial 'pop' album and was produced by the band themselves, as regular producer Gorwel Owen felt exhausted after a busy schedule working for other bands. Recording took place at Real World Studios, Box, Wiltshire in mid-1998 with the group experimenting with a sampler for the first time and writing a number of songs in the studio. The band tried to create a 45-minute long, immediate sounding record, and therefore chose the upbeat songs from the 25 tracks which were recorded during sessions for the album. Guerrilla was chosen as the album's title as a pun on the group's name.
