D-Rok was a British hard rock band notable for its Warhammer 40,000-influenced lyrics. At the beginning of the 1990s, Games Workshop began to diversify its activity, including combining its game world with music. As well as collaborating with death metal band Bolt Thrower, whose Warhammer 40,000-themed album Realm of Chaos was released on Earache Records, Games Workshop set up their own label, Warhammer Records, signing hard-rock acts such as Wraith and D-Rok. The band undertook a lengthy club tour to promote the record and secured a support slot with UFO and Wraith.
