Necros was formed in mid-1979 by then-teenagers Barry Henssler, Andy Wendler, and Todd Swalla. After going through a handful of bassists, Corey Rusk joined the band. Barry Henssler had struck up a friendship with Tesco Vee and Dave Stimson of Touch and Go magazine after sending them a copy of his own 'zine, Smegma Journal. Vee and Stimson became fans and put out the band's first record, a self-titled 4-song 7" EP most commonly known as "Sex Drive". This was Touch and Go Records' first release and was limited to only 100 copies. Andy Wendler left the band in 1981 and Brian Pollack joined on guitar. Later that year, the band recorded and released another self-titled 7" record known as "IQ32", produced by Minor Threat vocalist Ian MacKaye. This 9-song was jointly released by Touch and Go and MacKaye's own Dischord Records. Wendler rejoined on guitar in late 1982 and in 1983 the band recorded and released two more records, a 7" and LP both titled Conquest For Death. Early on, Necros played with many prominent punk bands, including Black Flag, Bad Brains, Sonic Youth, Minor Threat, and Tesco Vee's group The Meatmen. Necros also toured as openers for horror punk band the Misfits, including at the Misfits' last show in which Todd Swalla stepped in to play drums when Brian Damage became too drunk to perform. In 1983 Corey Rusk quit the group to concentrate on Touch and Go, after assuming full control of the label and bassist Ron Sakowski stepped in. Despite the group's steady output at their onset, the band did not release another record for two years. In an interview with One Solution zine, vocalist Barry Henssler blamed the delay between releases on Rusk's refusal to give the band a definite answer as to whether or not they were still on Touch and Go. The label has since deleted their Necros releases from their catalogue. The next Necros release came in 1985 as a split LP with White Flag entitled Jail Jello, on Gasatanka Records. Now featuring a more distinctly post-hardcore sound, the band followed up the split with 1986's Tangled Up LP on Restless Records along with a single of the same name on Gasatanka. After spending 1987 touring with first Megadeth and then later the Circle Jerks, the group called it quits. A live album, Live or Else, appeared posthumously in 1989.
Barry Henssler went on to form the band Big Chief, who recorded for the Sub Pop label. Ron Sakowski and Todd Swalla reunited in the mid 1990s as part of the final line up of Touch And Go artists Laughing Hyenas. Andy Wendler played in a group called Gone In Sixty Seconds. In 2002, a limited split 10" with Authority Abuse was released by Wise Hoodlum Records featuring live Necros recordings from 1981–1983. The band's first demo was reissued as the "Ambionic Sound" 7" in 2012, named for the studio where it was recorded. In 2005 Rykodisc reissued Tangled Up and Live or Else together on one CD, currently the only Necros material available on CD.
