An interview of John Adams

John Adams who is a prominent minimalist composer states music composer are not considered as a career. Minimal music repeats a bar for 2 or 3 mins. If one note went wrong or its too loud, then the audiences have to listen that error for 2 or 3 minutes as well. It seems that minimal music is easier than other genres of music, but the persist of the structure make it rather difficult to fix during the rehearsal or actual performance
