Manfred Montwé took a photograph of Prepared W.C., which was featured in Nam June Paik’s first solo show, Exposition of Music ― Electronic Television held at Galerie Parnass, Wuppertal, in March 1963. Paik suspended a mirror in front of a toilet and a plaster head upside down above it. As Peter Brötzmann sat on the toilet, the top of his head would touch the plaster head, and upon looking at the mirror, Brötzmann could observe four eyes looking back at himself. Paik wrote in his 1965 score Symphony No. 5, “3rd JANUARY, 14.68 to 21.00.08: Read for seven hours Baudelaire’s collected works, on the Prepared W.C. sitting like this genius, here Peter BRÖTZMANN (Federal Republic of Germany) or start on the toilet The Brothers Karamazov (Dostoevsky) to read and only come out again, if you have them!!” Attached next to these sentences were a photograph of Brötzmann sitting on the toilet of Prepared W.C. in Exposition of Music, and a newspaper clipping of the exhibition review from NRZ Wuppertaler Stadtnachrichten dated March 15th, 1963.
