Ticketmaster Mexico handed me a first row ticket but then wouldn't let me complete the purchase because my credit card isn't from the US or Mexico.
Oh well, hopefully date(s) in Aregntina will coincide with my time in Buenos Aires and Ticketek (?) will treat me better. Is Ticketek the most likely way tickets will be distributed?
And yes, by the looks of Ticketmaster Mexico it's Damien solo on the mini-tour, ie just him and his guitar. He probably just wanted a vacation in South America.
