I don't know if this is appropriate to post here, but I couldn't find anything against it, and the group is labeled as general discussion, so yeah. Anyways, I used to listen to an avant-garde experimental solo accordion piece created by a russian/soviet composer. I don't know if the composer was female but I think she was. Then it vanished out of YouTube for some reason, and I couldn't find it again. One thing unique about that piece is that there are places in the music where the keys are mashed to create tone clusters, and the sheet music for it has some parts where glissandos are notated very T H I C C and huge, for some reason. Also some parts have odd rhythm subdivisions I think. Does anyone have an idea about what is it? Thanks in advance!
