Nocturnus was formed in Tampa, Florida back in 1987 by drummer/vocalist Mike Browning,bassist Richard Bateman & guitarists Gino Marino and Vince Crowley. Very soon, band recorded the first self-titled demo "Nocturnus" on a 8 track reel to reel machine. Demo had a four songs:BC/AD,Nocturnus,Unholy Fury and The Entity.(The last two songs can be found on the Acheron`s "Lex Talionis" CD with Vince Crowley on guitar-who actualy wrotted them and Mike Browning on drums).
After Vince quit Nocturnus 1988 to start his new band Acheron, he was replaced by Gino`s cousin Mike Davis.Then Richard Bateman was offered the bass position in Nasty Savage and quit Nocturnus to join Nasty Savage. Friend of Mike Davis, Jeff  Estes replaced Bateman. Keyboardist Louis Panzer who was actualy friend of Davis and Jeff  joined in September 1988, which added another dimension and completed the Nocturnus sound. They were one of the first bands to do technical death metal using horror themes in their music. 
In 1988 they released ‘The Science of Horror’ demo produced by Savatage singer Jon Oliva, which had four songs from ‘The Key’ album. This demo caught the eye of Digby Pearson at Earache Records in Nottingham, England and subsequently they were given a record deal.
Sean McNenney,close friend of Davis, replaced Gino Marino as one of the guitarist for ‘The Key’ sessions. Once the album was released it went over big in the metal scene selling over 50,000 copies worldwide. ‘The Key’ had technical guitar work that was not seen in death metal and therefore it blew everyone away. ‘The Key’ was also the first album by a death metal band to work keyboards into every song.

 

After leaving Nocturnus, Gino Marino made it to Atlanta, Georgia, where he started a new band called Euphoria. They recorded one demo, started working on some new material then Gino disappeared. According to Bob Vincent that demo really kick ass – it blows Nocturnus out of the water (and Bob likes Nocturnus). The new material that they were working on was supposedly even better than that demo, but unfortunately none of it was recorded. Gino sent Mike Browning copies of that demo, possibly with the idea of them working together again.
After recording of "The Key" Jeff Estes was replaced by Jim O'Sullivan, who toured with the band and then was fired before Thresholds was recorded. Nocturnus toured Europe in 1991 with Bolt Thrower and was amazing crowds with their live performances of those gripping songs. The Grindcrusher tour of the US with Napalm Death and Godflesh was up next.
 After the two tours with Bolt Thrower, Napalm Death and Godflesh, Nocturnus went into the studio to record ‘Thresholds.’ Dan Izzo was brought aboard to do vocals for Nocturnus. This was a great relief for Mike Browning who could now concentrate on drumming. It also brought a better stage presence to the band. Chad Anderson replaced Jeff Estes as the bass player, but he only played bass during the recording sessions of ‘Thresholds.’ Jim O’Sullivan was recruited as a touring bassist. Emo Mowery joined in 1991 to replace their touring bassist Jim O’Sullivan for the tour with Confessor following the release of ‘Thresholds.’ Thresholds was released in 1992 on Earache Records. This was to be their last record for Earache.
Shortly after founding member Mike Browning(who was actually the drummer and vocalist in an early Morbid Angel,and drummer in Incubus) left Nocturnus, James Marcinek was brought in to replace him.That also signed the end of the early "evil" Nocturnus. Dan Izzo was still on the vocals. In 1993 they recorded a two-song 7”/MCD for Moribund Records in Seattle, Washington. This 7”/MCD contain two of the great songs from Nocturnus.Once the 7”/MCD was released Nocturnus broke up.
Seven years after the last Nocturnus record was released comes Nocturnus back stronger than ever. Sean McNenney and Mike Davis are back to bring us their unmistakable sound, and Louis Panzer is still making those eerie sounds on the keyboard. Emo Mowery, the bassist for the 7” now adds the vocal duties, since Dan Izzo is not with the band anymore. Rick Bizzaro, the newest member of Nocturnus, is taking over on drums. In 2000, Nocturnus release ‘Ethereal Tomb’ on their new record label Season of Mist Records in France. This album is a great album that still uses the sci-fi themes today as it did back in 1988 when they formed.
The keyboardist, Louis Panzer, has left Nocturnus in August 2000. Soon, Nocturnus were disbanded again.
