        Madcat's music has been evolving for over 60 years. It started in the Chicago area in the early 1960s, with Madcat playing folk/blues on guitar and harmonica. By the late 1960s, he had immersed himself in the Chicago Blues and was studying harmonica with Big Walter Horton. In the early 1970s, Madcat moved to Ann Arbor, Michigan where he was a key presence in two of Ann Arbor's finest progressive rock bands: New Heavenly Blue and Sky King. By the mid 1970s, Madcat was touring the world with jazz pianist Dave Brubeck. In the 1980s, Madcat went solo infusing the folk/blues tradition with elements of rock and jazz. In 1990, Madcat teamed up with guitarist/singer Shari Kane to form the duo Madcat & Kane. For twenty-four years they toured nationally and internationally. And in 1998 Madcat teamed up with Chris Brubeck to form Triple Play and also started performing with Big Joe Manfra in Brazil. Madcat currently fronts Peter Madcat Ruth’s C.A.R.Ma. Quartet.

Quotes about Madcat

      "Madcat has got to be one of the greatest jazz soloists in terms of getting an audience. He's got that magical quality. It doesn't matter if he's playing a hoe-down kind of thing that evolves into a blues and pretty soon into jazz. Audiences here and overseas go with him all the way. He's into music without categories."
