that brings to mind Stravinsky's The Rite of Spring conducted by the composer himself.
it was the worst i've ever heard.

the best one i heard was played by students at a university's music school in Toronto in the late 70s. it was a year end show. By the time i could get up and applaud, the musicians were leaving...

as the french (in France) say: c'était le délire!
