High Quality Content by WIKIPEDIA articles! Rainer Ptacek (June 7, 1951 – November 12, 1997) was a Tucson, Arizona based guitarist and singer-songwriter. His guitar technique, which incorporated slide, finger-picking, tape loops and electronic manipulation, earned him admiration of some notable musicians such as Robert Plant and Billy Gibbons. A tribute album to Ptacek, The Inner Flame, included contributions by Plant, Jimmy Page, PJ Harvey, Emmylou Harris and others, and was indicative of his reputation as a "musician`s musician". He was diagnosed with a brain tumor in early 1996 and died nearly two years later after the illness recurred.
