Construction takes place on the gigantic stage for U2's 360 degrees tour which opens in the Nou Camp on 2nd July 2009. Barcelona, Spain - 12.06.09

The band kicked off their global trek in Barcelona on Tuesday (30Jun09), but spent days rehearsing there beforehand.

A city resident complained about the excessive noise after the rockers played longer than agreed by local officials.

Bono and his bandmates were allowed to practice until 10pm at the Camp Nou stadium - but on one occasion they rehearsed until midnight, according to a local newspaper.

They face a fine of 15,000 Euros (US$21,000/£12,800) under noise pollution laws.

Local businessman Alfons Huescar says, "While business outlets cash in on fans flooding in, residents can't even open their windows at home."
