 Most bands of the NWOBHM had the same look as their fans and produced rock shows without special visual effects . A notable exception was Iron Maiden , which created the grisly character Eddie the Head as a stage prop to enrich their performances very early in their career . Other exceptions were Demon , Cloven Hoof and Samson , which used various props , costumes and tricks in their shows , while Pagan Altar and Venom became well known for their elaborate scenography inspired by shock rock and Satanism .
