Good morning. Yes, we have another two big outdoor shows to announce for next summer. On Monday 31st August 2009, Coldplay will be playing at the Stadio Friuli in Udine, Italy. A few days later, on Friday 4th September, they'll roll into Barcelona, Spain to play at the Estadi Olimpic. Tickets for the Udine show will be available on Tuesday (Dec 16th) from ticketone.it, while the Barcelona show will be onsale from Wednesday (Dec 17th) from livenation.es.
