not sure if I'm ok to post this on here but anyway
The official website of the Japan Expo has put online a poll of 5 questions regarding J-Music.
1. Which kind of artist you would like to see?
2. Which night you would prefer to see the concert?
3. What is the duration do you expect for a concert?
4. What is the price you find acceptable to see a super artist you like?
5. What is the artist/group you want to see with these conditions?
French readers can now take the poll

The convention will be held this July in France.
