Breed 77 comes from the British overseas territory of Gibraltar. Old Gibraltarian school friends; Paul Isola, Danny Felice, Stuart Cavilla met up in London and became informally known as the Gibraltarian Mafia. When, in late April 1996, this circle of friends formed a band, they wanted a name to reflect their joint origins and called themselves simply Breed. The band were forced to change their name because it was previously registered by Steve Hewitt (formerly of Placebo) on his vanity record label. Stuart Cavilla, the band's bass player, had previously worked as a motorcycle courier under the call sign of Kilo 77 or K77, and the band became Breed 77.
Breed 77 released their third album In My Blood (En Mi Sangre) internationally on 11 September 2006. In My Blood (En Mi Sangre) was produced by Ron Saint-Germain (The Saint) noted for his work with Soundgarden, Tool, Creed and Bad Brains. Two bonus tracks were produced by Greg Haver (Manic Street Preachers). The first single from this album, "Alive") was out on 12 June 2006, also known as Download Monday, and reached number 6 on the Rock Singles Chart. The second single was "Blind", released on 4 September 2006. Their last single to date is "Look at Me Now", released on 23 April 2007. The single includes a special cover of the song 'Zombie', by The Cranberries.
In early 2007, the band released the iTunes exclusive album Un Encuentro (to coincide with the launch of "iTunes Latino". The album featured 11 songs from previous albums but all sung in Spanish. This album was re-released in physical CD format on 7 May 2007.
The band is currently writing and demoing their 5th studio album, as of yet un-named. Recording is planned for summer-time and release for early Autumn 2008. The first two tracks have been announced as "The Horns of Hattin" (April 2008) and "Wake Up" (July 2008).
They headlined a UK tour in September 2006. Breed 77 played at Santa Cruz X 103.9's Jingleballs concert on December 6 2006, in Santa Cruz, California. It was their second live U.S. performance.
