Almac has 2 Diamond Head concerts.

Diamond Head are an English heavy metal band formed in 1976 in Stourbridge, West Midlands. The band was part of the new wave of British heavy metal movement and is acknowledged by thrash metal bands such as Metallica and Megadeth as an important early influence. Brian Tatler formed the band with drummer Duncan Scott while both still at school. In June 1976 they found singer Sean Harris, who was in the same year, and went through three bass players before settling on Collin Kimberley in Feb 1978.
