In the middle of 1999 Mike Browning (vocals, drums), Richard Bateman (bass), and Gino Marino (guitar) - all of the first original line-up of Nocturnus in 1987 - reformed as Nocturnus A.D. with Mike Walkowski on guitar replacing the only other original member from 1987, Vincent Crowley (Acheron).
The name was changed to After Death in 2000 so it would not be associated with Nocturnus. The band again performed as Nocturnus in 2013 for selected shows, though they may not do so in the US due to copyright issues.
The band recorded an EP titled "Vibrations" in 2000, but it was released only as part of the "Retronomicon" compilation in 2007.
In 2013, Nocturnus A.D. was reformed again with the same lineup as After Death.
