Raven - Leave Em Bleeding

Fakta Experts agree: Without Raven, neither thrash nor speed metal would
exist in their current form. The British trio around the Gallagher
brothers John (bass, vocals) and Mark (guitar) not only released some
of the most important albums of the NWOBHM era, but they also had
a lasting influence on an entire generation of musicians in the early
1980s.
