A story told to me thirty years ago...relayed a the details of a Eastern U.S.A. performance (probably apocraphal) about Andre Segovia
He entered stage left....with a guitar in hand...he sat in a chair...and played an astounding piece....a brillant, dynamic opening number, the audience was awed,,,,,,and then he smashed the guitar to pieces / smiterins against the stage....and announced.
"Most of you probably assumed that I destroyed an heirloom antique, multi-thousand dollar insturment.... it was not....it is one that I picked up and hour before the performance at a five and dime store for 30.00...... it is not the insturment....it is the performer."
From what I understand of A.S. he was a very humble performer and it is difficult to invisage such a flambouyant demonstration....and yet....it is hard to predict anyone's outrage against ignorant critics on any given day.
