Primal Fear is a German power metal/ heavy metal band formed in 1997 by Ralf Scheepers (Vocals/Ex- Gamma Ray), Mat Sinner ( Bass and Vocals/ SINNER), Stefan Leibing and Tom Naumann (Guitars). Their style is a heavy power metal sound with the Halford-esque vocals of Ralf Scheepers that give a feeling of Judas Priest's Painkiller era.
