Negative FX was a hardcore band from Boston, MA, formed in the early 80's. They played five shows during their brief existence. The band was well known for their involvement in the local straight edge scene of the early 80's. Along with members of the bands DYS and SS Decontrol, Negative FX helped to form a group known as the Boston Crew, a notoriously violent group of kids who held a strict, and almost militant, view of the straight edge mentality.

Negative FX played an incredibly fast and largely unmelodic form of hardcore punk, that featured frequent gang vocals shouted along with the chorus. The band members consisted of Pat on guitar, Rich on Bass, Dave on drums, and their high profile vocalist Jack Kelly, who frequently went by the name of Choke. Choke went on to later form the band Last Rights, then Slapshot.

Negative FX has released only one self titled album, which was recorded in April and November of 1982 at Radiobeat studios in Kenmore Square, but wasn't released until 1984 on Taang! Records. It was re-released on blue vinyl by Taang! in 1989 and more recently on the German label Reflex Records in 2002.
