Aerosmith played the Stone Festival in Sydney, Australia on April 20. Video clips of the performance are just now starting to pop up on YouTube. I followed along on Twitter during the show a little. The consensus seems to be that Van Halen sounded lousy due to a poor sound mix and Aerosmith should have headlined. I could have told you that, but I'm biased. I think I read awhile back that Aerosmith and Van Halen got three million bucks to do the fest. Not a bad payday for 90 minutes of work each!
