2007 European Festival Ideas??

Wow, it has been a long time since I last visited hipforums..I needed some good vibes!
I'm going to be moving to London, UK in January and remaining there until the end of June. I plan on doing quite a bit of traveling (though 'home' will be London) I was curious to as some good Eurpoean festivals in that time frame that you all have attended in previous years or heard about. I didn't find much through searching the forums...
Thank you all so much.
In Peace
