Ok, this is a blog I check regularly, although I don't know Korean well, but this person goes to concerts very often and tends to record them. And YES, this time she went to ARENA TOUR and now you can listen to some songs live:
[MY] 2009.06.21 ayumi hamasaki - Boys & Girls
[MY] 2009.06.21 ayumi hamasaki - Curtain call
[MY] 2009.06.21 ayumi hamasaki - evolution
[MY] 2009.06.21 ayumi hamasaki - GREEN (...which is Days, actually)
Curtain Call sounds awesome!
Enjoy!
