August 9-11 in Golden Gate Park will have legendary artists (Paul McCartney, Willie Nelson, and others), and artists you love today (too many to list here).  The full line-up can be seen at http://lineup.sfoutsidelands.com/.

Pick your favorite and go with a friend with these two passes.  They are good for just one day of the festival, and it is a festival with food, drink, and art in addition to the great music.
