First started with (also ex-Purgatory guitarist) Dave Felton's former bandmate from his time in Centurion, Sam Romano on drums.
He was replaced by Gary Estok in late 1989, who appeared on "Sins Of A Bastard Angel", the first song released by the band.
In early 1990, they solidified the lineup that would last the rest of their career when Estok was replaced by Trëllebörg drummer Steve Felton, and Trëllebörg guitarist Marko Vukcevich was brought in as the 2nd guitarist for their live performances.
Hatrix played their first live show at the Phantasy Theater in Cleveland, at the Heavy Artillery Pre-Release Party on December 16, 1989.
Hatrix re-united in 2003 for a stint of shows in the Cleveland area lasting until Summer 2004.
