Irving Conrad Ashby (December 29, 1920 – April 22, 1987) was an American jazz guitarist.
[1] Ashby was born in Somerville, Massachusetts and started playing guitar when he was nine.
[2][3] He then briefly replaced Charlie Smith, a drummer, in the Oscar Peterson Trio,[4] producing a line-up (piano, guitar, bass) similar to the Cole Trio's; the substitution of a guitarist for a drummer continued until 1958.
After leaving the Peterson Trio, Ashby concentrated on session work, which included recording with Norman Granz, Sheb Wooley, LaVern Baker, Howard Roberts, B.B.
In addition to guitar, Ashby played the upright bass.
