 The tracks were originally made as raw material for other releases and were not intended for release themselves.While working on cassette reissues for Blossoming Noise in 2009, Masami Akita rediscovered the original four track master tapes, and found that they could be considered "completed works of improvisation music" of their own.When Merzbow started playing live internationally in the late 1980s, it required the use of simple and portable gear, which then influenced Akita's studio sound, leading to the harsh noise style he became known for in the 1990s.
