Musical Instruments
The cassette culture (also known as the tape/cassette/mixtape scene or cassette underground) is the amateur production and distribution of music and sound art on compact cassette that emerged in the mid-1970s. The cassette was used by fine artists and poets for the independent distribution of new work. An independent music scene based on the cassette burgeoned internationally in the second half of the 1970s.
