John Connelly (born July 28, 1962) is an American musician, best known as the lead vocalist and guitarist of New York City thrash metal band Nuclear Assault.

Area musicians Patrick Vitagliano, lead guitar, Tony O'Brien, bass and Tom Maynard drummer from Senslis Killin' were recruited to perform gigs and support new material.

The direction for the new material was heavy guitar oriented music combining elements of punk, thrash, and speed metal with some blues thrown in occasionally.

The setlist typically contained the songs "L. H. A", "Aggressive", "7/8 Solution" from "John Connelly Theory" and "Another Violent End", "Behind Glass Walls" and "Hang The Pope" from Nuclear Assault's catalog.

About this time the band relocated to Pawcatuck, CT. On May 14, 1997, John reunited with Glenn Evans, Dan Lilker and Anthony Bramante for one Nuclear Assault show at the Colosseum in Manchester, NH.

They played the classic NYC venue CBGB in May along with a show in Massachusetts that was recorded for a live album to be released on Screaming Ferret Wreckords in early 2003.

After a well-received performance at the Wacken Open Air festival in Germany in August, original guitarist Anthony Bramante left the band due to commitments at home and was replaced by Erik Burke.

Lyrical themes on that album include broad criticisms of holy war, and the song "Price of Freedom" is specifically about the response of the United States after September 11, 2001.
