The British heavy metal band Diamond Head has had a major influence on the world of metal music over the last forty years. 

Formed in 1976, the band released their first two albums independently in the early 80's before singing with MCA Records.  That early music found its way to the ears of groups like Metallica and Megadeth with the former covering a number of Diamond Head's songs in their early shows. Even as recent as a few weeks ago, Lars Ulrich announced his new weekly radio show, "It's Electric", named after the early Diamond Head song and using it as the theme. 

After a couple of breakups, the band reformed in 2000 and have been going strong ever since, including their latest, self-titled, album which was released last year.
