Are you rested or weary?  How was your first weekend of Jazz Fest?  The answer to those questions may determine how you spend today.  I would recommend heading back to the Louisiana Music Factory- you did go last Thursday didn’t you?  It’s eight full hours of music starting with Big Daddy O at 12 noon and ending with Big Sam’s Funky Nation at 7 PM.  If improvisation is more your style, two of the masters will be playing at the Big Top at 8 PM.  The German saxophonist Peter Brotzmann and the Chicago-based drummer Hamid Drake (pictured) will likely tear off some heads in a freewheeling duo performance.
