Nocturnus

"Ah, but there was more to Floridian death metal than pure savagery, and Nocturnus, from – where else? - Tampa, proved it with their daring and progressive style. First formed in 1987, Nocturnus were among the first death metal bands to incorporate keyboards into their sound, and their lyrical focus on science-fiction offered a refreshing alternative to death metal’s prevailing preoccupations with Satan and gore during those early years. Heck, even today, 1990’s ‘The Key’ remains an awesome achievement, well ahead of its time, and Nocturnus would deliver a second worthy LP in ‘92’s ‘Thresholds,’ before sadly losing steam and shutting down their space station for many a year."

"It wasn't unusual for mainstream metal and hard rock bands to use keyboards, but it was hardly typical in the underground world of death metal, thrash, and grindcore. Nocturnus, of course, didn't want to be typical, which is why The Key is among the more interesting death metal releases of 1990."
