In its original incarnation, Siege paired extremely fast tempos with vocalist Kevin Mahoney's screeches and growls in their intense style of hardcore.

Though little known at the time, the band has posthumously become revered by punk and heavy metal fans worldwide and is now regarded as one of the pioneers of the grindcore and powerviolence subgenres.

[2] Guitarist Kurt Habelt, bassist Hank McNamee, and drummer Rob Williams rehearsed together informally during this time.

They completed Siege's classic lineup in 1983, recruiting vocalist and occasional saxophonist Kevin Mahoney from nearby Braintree.

In October 1984 the band recorded three more songs at Radiobeat with Giordano for Pushead's classic 1985 hardcore compilation Cleanse the Bacteria.

[3][7] They played in Greenfield with local hardcore bands DYS, Cancerous Growth, The Freeze, B.I.U, Outpatients, and Deep Wound, out of state at the Living Room in Providence, and at Anthrax in Stamford.

Their tracks on Cleanse the Bacteria exposed them to wide audiences, including Lars Ulrich of Metallica, who described them as the fastest band he had ever heard.

Relapse Records officially released Siege's demo and compilation tracks in 1994 as the Drop Dead CD.

Williams remained musically active and formed the band Nightstick,[12] which additionally featured Putnam and Habelt at times.

[15] Williams occasionally performed Siege material live with the Providence band Dropdead, including at Mayland Death Fest in 2014.

This live group was completed by vocalist Mark Fields, second guitarist/bassist Chris Leamy (bandleader of Brian Famine, and a member of Japanese Torture Comedy Hour with Pig Destroyer guitarist Scott Hull), and Ben Barnett from Dropdead.
