Paranoia were started when few people believed in thrash metal and few bands came with the idea of doing thrash metal and similar music in the entire world, less in Spain, but Paranoia had the personality to fight against the death of thrash metal, supported by music of bands like Pantera, Machine Head and Sepultura. Influenced by bands like Legion, Soziedad Alkoholika, Hamlet and Ktulu from the Spanish thrash scene and also obviously by the masters of thrash of other countries, Paranoia ever tried to mix the influences and get own personality and something different.
