Graham Haynes on improvisation: You must be totally prepared, but you must also be empty

"Ultimately you must be totally prepared but you must also be empty. Empty of pre-conceived ideas on what you practice or study at home. You can use these ideas which you practice and study but only if it serves the music at hand at the necessary moment. It's not much different from theater acting in that way" - corneter and composer Graham Haynes said in 15 Questions interview about improvising. His collaborative album 'Echolocation' witch producer Submerged is out now.
