ah Nocturnus. they broke up after releasing Thresholds in 93 i think, dunno why.... i guess no steady lineup and changing musical trends.... anyway they got back together in 99 and released ethereal tomb.... but then broke up for good, dunno why. yes, nocturnus were amazing, when i first checked them out i though they were just gonna be an average death metal band with just the whole sci-fi gimmick, but no, the first thing that wowed me were the guitarists, they were amazing. Thresholds is probably my all time favorite guitar album.
