Only been there twice, definitely going for the third this upcoming summer, so I should've probably waited until after that one before making this list. But fuck it, I'm bored at the moment anyway...
1. RADIOHEAD --- 2008
My first ever concert at the mighty Orange stage, and actually my first open air "stadium" size concert ever. Amazing atmosphere, nearly perfect setlist, perfect performances of the songs they DID play. The rock-show I'm still comparing every other rock-band gig to.
2. THE STREETS --- 2008
Even better atmosphere than at Radiohead the evening before. I've never felt such magical unity and shared happiness with both the fellow audience and the artists on stage, before or since. Mike Skinner still calls it the greatest gig of his life, and I'm so thankful that the ONE Streets show I got to be at before he retired, was this one.
3. PRINCE --- 2010
Felt at times like a celebration of everything I love about music. Went to some great concerts in '10, but it kinda kept missing the 'show of perfection'. And then this little genius and his band delivered exactly that during the very last show I attended.
4. PATTI SMITH --- 2010
By far the best daytime-concert I've been to at Orange stage so far. Didn't know much about her and hadn't heard many of her songs before the festival, but this show instantly made me a huge fan.
5. BROTHER ALI --- 2010
Best rap-concert I've been to so far at Roskilde, and actually one of the best I've been to in general. Ali handled the classic stripped down "one MC with his mic, and a DJ on the decks" live Hip-Hop format better than anyone else I've seen.
Chemical Brothers --- 2008
The Prodigy --- 2010
Muse --- 2010
