[Dixielandjazz] For the percussionists:

[M J (Mike) Logsdon]

The symphony musicians had little confidence in the person
brought in to be their new conductor. Their fears were
realized at the very first rehearsal. The cymbalist,
realizing that the conductor did not know what he was
doing, angrily clashed his instruments together during a
delicate, soft passage. The music stopped. The conductor,
highly agitated, looked angrily around the orchestra,
demanding, "Who did that? Who did that?"
