Argentina's La Viola conducted an interview with METALLICA drummer Lars Ulrich and filmed the band's January 21, 2010 performance at the River Plate Stadium in Buenos Aires. Watch the footage below.

A policeman was injured and 120 people arrested when rioting broke out outside METALLICA's January 26, 2010 concert in Santiago, according to the Latin American Herald Tribune. Authorities said that most of the arrests were made when hundreds of fans who did not have tickets attempted to force their way into the Club Hipico horse-racing grounds to see the show, which was attended by a crowd of more than 50,000. Police colonel Miguel Angel Castro said, "A group of people tried to enter without tickets and Carabineros (militarized police) had to act, launching water."

Charges against those arrested included disorderly conduct, drug possession and drinking in public.

The gig was the sixth on METALLICA's current South American trek, which began on January 19 with the band's first-ever appearance in Lima, Peru. The crowd of 55,000 at that show was the biggest for a musical event in Peruvian history.

The group wraps the first leg of the jaunt this weekend in Brazil, resuming in early March with stops in Mexico, Guatemala, Costa Rica, Venezuela, Panama and Colombia.
