Probably none. I'll possibly be going to the Big Green Gathering festival but they don't have big names, and I'll be too busy running a bar to watch any that aren't on in the marquee where I'll work.
I saw RHCP last year (or 2 years ago?) and they were completely shit. Played 1 old song and the rest were mellow and new and so I didn't know them. Rubbish!
