Stephen Patrick O'Reilly (born September 2, 1964), better known as Stephen Egerton, is an American guitarist, best known for his work playing with Descendents and All.
Egerton was raised in Utah and played drums and guitar in the seminal Salt Lake City punk rock/death rock band Massacre Guys from 1980 to 1985 alongside bassist Karl Alvarez. In 1985, Egerton moved to Virginia, where he studied classical guitar and played in the band Auto Da Fe with former Iron Cross vocalist Sab Grey, prolific DC area drummer Eric Wallgren, and former Black Market Baby bass player Paul Cleary, until joining Alvarez in the Descendents in late 1986.
The appearance of Egerton and Alvarez marked a turning point for the Descendents and their allied band All; for the first time, drummer Bill Stevenson found himself alongside players with the same manic, obsessively-correct technical virtuosity as he. Egerton's guitar playing is marked by a dexterity, precision and inventiveness rarely equalled in the pop-punk genre. This virtuosity was immediately evident on songs like "Iceman", "Schizophrenia" and "Van" from the Descendents' 1987 album All. Egerton has continued to refine and develop his style in each subsequent release by consciously adopting lashings of retro-rock riffage and slurred soloing to balance the near-scientific quality of his playing.
