 Since the beginning of the NWOBHM , North American bands like Anvil , Riot , Twisted Sister , Manowar , Virgin Steele , The Rods , Hellion , Cirith Ungol , and Exciter had a continuous exchange with the other side of the Atlantic , where their music was appreciated by British metalheads . In this climate of reciprocity , Manowar and Virgin Steele initially signed with the British indie label Music for Nations , while Twisted Sister recorded their first two albums in London .
