1987, raging FAST Thrash/Speed assault clearly influenced by SLAYER's "Reign in blood" or for comparisons, think of other extreme Californian acts like Dark Angel, Slayer, Sadus (sans the loud bass), Vio-Lence and perhaps later Hexx (when they switched to thrash metal), and you'll get a pretty fair idea of what Viking were pushing. An outburst of ragingly furious riffs with agitation vocals that strike at ultra fast speed like machine gun fire massacring innocent Christian victims. Straight forward pulsing muffled strum streams of frenzied mayhem killing all in sight; it is incendiary riot-thrashing metal!
