Back in 1982, when the first Atonal Festival happened in Berlin, tapes were widely distributed. They were a normal way of recording and listening to sounds. They were also often used in experimental circles to play with sound. This is the case in the video above which features footage of Alexander Hacke of Einstürzende Neubauten fame performing live with tape at said festival. With the recent renaissance of the cassette tape, it’s interesting to see what the forebearers of the medium came up with back in the day.
