Every Friday I turn the blog over to Dan Marsicano for his Retro Recommendation, giving you a chance to learn about underrated and overlooked gems from metal's past. In November, we are spotlighting New Wave Of British Heavy Metal (NWOBHM) bands. This week, the spotlight is on Holocaust. They were a big influence on Metallica, who covered their song "The Small Hours" on their 1987 covers EP. Holocaust's 1981 debut The Nightcomers is this week's Retro Recommendation.
