This discography of musical work by the bassist Peter Kowald, who died in 2002, was compiled in honor of his 70th birthday. It includes an alphabetical catalogue of all 143 published recordings up to 2014 by and with Peter Kowald, as well as the cover designs and additional information relevant to the discography. The 208-page book also contains an index of all the films that Peter Kowald was involved in, texts by Bert Noglik, Floros Floridis, Wolfgang Schmidtke and Günter Baby Sommer, and several photos and drawings by Peter Kowald. A register of all the participating musicians makes this discography into a scholarly reference work of 20th century music history. Kowald (1944-2002) was a vital figure in German free jazz, playing for many years with the Globe Unity Orchestra, the Schlippenbach Quartet and with Peter Brotzmann, on to periods living in Greece, Japan and in New York. He worked in a vast amount of settings from solo and duo bass recordings to dance and film work. The four CDs here offer a selection of studio and live recordings, including the Grandmothers Teaching session with Chris McGregor, Harry Beckett etc, and two rare albums recorded for small Greek labels: Aphorisms (1997) and The Human Aspect (1990)
