"In the middle of the concert I require to, as Wayne Shorter would say, take a backwards flip into the unknown. I need 20 minutes to half an hour where nobody knows, including myself, what we're going to do. Not the light man or the sound man. So you can dip into what's not written, beyond the mechanics, the intangibles." -- Carlos Santana (b. 1947-07-20), interviewed by Tavis Smiley on the PBS television program Tavis Smiley, 2009-04-02
