My friends ask me to take a guess as to who will perform at Summerfest 2011. I don't have a crystal ball. In fact, it's a well kept secret as to who is being courted by Summerfest management. We won't know until the ink is dry on a contract.
What I can say is that history has proven that there is usually an announcement in late March. The first Marcus Amphitheater act is booked around that time. More announcements trickle in as spring comes. The rumors may fly, but few people ever guess the right guess.
One other thing we have come to expect is the genre of music, and how many nights each is represented. There will be rock, pop, soul, country, and more. I'm not an insider, so I will wait with the rest of you.
