Thanks frogman for this very interesting article about musicians who are music itself...
All composers are first and last musician who could "interpret" their own work but any work of genius exceed his creator...They can interpret their own work but without ever exhausting it if it is a deep one...
Art of music is so deep,no one master it once for all even his own works escape the creator with a life of his own...
Simple evidence : each new interpretation of the art of the fugue on any set of instruments non intended by Bach reveal something new...
To feel bored listening to Bach or Josquin Des Prez pass my understanding and my perception...
I am never bored by great musicians who play any great work or improvised masterfully...
