Genre: Hip Hop/Rap
Holocaust is a heavy metal band which is based in Edinburgh, Scotland, founded in 1977 while still at high school.
Influenced by Black Sabbath, Judas Priest, Motörhead, UFO, Led Zeppelin, Rush and Budgie, the original lineup featured guitarists John Mortimer and Ed Dudley, vocalist Gary Lettice, bassist Robin Begg and drummer Nick Brockie. In 1983, guitar player Ed Dudley left the band, forming and releasing an album under the moniker Hologram.
Hologram's album "Steal the Stars" was a much more radio-friendly release, presented by Dudley as the official continuation of Holocaust, yet in 1984 John Mortimer revived the Holocaust name, releasing the first of many albums with himself as vocalist, guitarist and sole original member.
