Roma, Gianna Nannini
Genova, Jovanotti
Bologna, Gianni Morandi

Torino, Subsonica
Napoli, Daniele Silvestri
Lamezia Terme, Caparezza
Lodi, Elio e le storie tese
Riccione, Nomadi
Milano, Fausto Leali

Which one are you going to? I'll switch places with you for New Year's Eve, 'k?? ...you can come to Atlanta GA and sit here at my desk, then drive for one hour to get home, then sit out on the deck out in the boonies, light a few firecrackers ...and go to bed at 1 a.m.
Happy NEw Year!

i didn't go to a concert, I' preferred a party in house with a good dinner and some friends, but in Rome to the concert of Gianna Nannini there were 200.000 persons, from Colosseo to Via dei Fori Imperiali.. really spectacular..
