Festival Season in the U.S.

Hey we got tons of big music fest in the U.S. going on right now. They just had a big neo-hippie fest down in Tennessee with Trey (from Phish) Widespread Panic (big in the south) Ween, and a bunch of other "Jam" bands playing for over 70,000 trustafarians and frat boys and girls. How about over in Europe? What are the big fests.

(My sister flew to London about a week ago for a few days before they went to Croatia and I told her to pick up Ians Musical Spheres because was not released in the U.S. How is this album compare his past two releases?)
