Tampa, FL d**h metal band Nocturnus was formed in the late 1980s by singer/drummer Mike Browning, guitarists Mike Davis and Gino Marino, ba**ist Jeff Estes and keyboardist Louis Panzer. Following the demo Science of Horror, the group swapped Marino for guitarist Sean McNenney prior to recording its 1991 Earache label debut The Key. Vocalist Dan Izzo signed on for 1992's Thresholds, which also saw ba**ist Chris Anderson substituting for Estes; Anderson himself was replaced by ba**ist Emo Mowery for Nocturnus' third album, a self-titled 1993 release for the Moribund label -- the record was also the first without Browning, who turned over his drumming duties to James Marcinek. The group soon dissolved, reforming in 1999 around a roster of Davis, McNenney, Panzer, Mowrey and drummer Rick Bazzaro to record the comeback effort Ethereal Tomb. ~ Jason Ankeny, All Music Guide
