Peter Madcat Ruths music has been evolving for over forty 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, where he was a key presence in two of Ann Arbors finest progressive rock bands, New Heavenly Blue and Sky King. By the mid 1970s he was touring the world with jazz pianist Dave Brubeck. In the 1980s he began performing solo, infusing the folk/blues tradition with elements of rock and jazz. In 1990 he teamed up with the guitarist/singer Shari Kane to form the duo Madcat & Kane, since when they have been touring nationally and internationally. In 1997, The Society for the Preservation and Advancement of the Harmonica (SPAH) honoured Peter Madcat Ruth as the Harmonica Player of the Year.
