Xenomorph
1.) Dutch Death Metal band XENOMORPH was founded in 1992 emerging from the underground scene in The Netherlands. Their most steady line-up became: DeTombe (vocals), Coert Zwart (guitar), Kreft (guitar), JRA (bass) and Marc Bomber (drums). They most likely got their name from the "scientific" predicate given to the aliens starring in the Aliens movie series. Their lyrics are mostly about evil, Satan, and other dark and occult stuff more than once inspired by the work of artists like H.R. Giger and Sir Ridley Scott.
