When I was a child and played the fiddle, a couple times a year the teachers would dress us all up smart, range us in a hemicircle on the dusty boards of the local Culture Palace and set us to screeching & scratching. Probably the most beautiful music I've ever heard has been produced by such arrangements of forces, and has been striven after in vain by more sophisticated & self-conscious collaborations. Back in Soviet days we used to get occasional visits from some of the lights of Lenigrad & Moscow free-jazz. One underground concert of that stamp was all any reasonable person needed before they were converted forever toward the purer pleasures of the official stage: the child violin-gang.
