Demolition Hammer arrived on the East Coast thrash metal scene circa 1986. The original line-up consisted of Steve Reynolds as the vocalist and on bass, James Reilly on guitar, and John Salerno on drums. Their first demo tape, Skull Fracturing Nightmare, was released in 1988. It gained notice from fans of the genre and independent record labels. Derek Sykes was brought in as a second guitarist and Vincent Civitano (a. k. a. Vinny Daze) replaced Salerno. Their second demo, Necrology, secured the group a recording contract with Century Media Records.
