Effective period / Period of releases: 2004

Spanish RAC band formed inside Alcalá-Meco prison by National Alliance spokesman Eduardo Clavero. Clavero served as the band's composer, guitarist and vocalist. Although able to perform concerts in this prison and even release concert tapes to outside audiences, the band underwent erratic line-up changes because members were frequently transferred to other prisons.

Upon release from prison, the band recorded and released three albums.
