Mick Jagger's not the only one who can't get no satisfaction.

More than 30 fans were injured and nearly 90 people detained at a Rolling Stones concert in Buenos Aires Thursday when a throng of ticketless fans fought with police to enter the sold-out venue.

Argentinean officials said the rowdies clashed with the show's security detail while attempting to storm the gates of the Monumental soccer stadium, which holds some 50,000 and where Mick and the boys were set to perform.

The conflict quickly turned into a full-blown fracas as police fired rubber bullets and water cannons into the crowd to quell the uprising. Officers also clubbed particularly unruly fans, who reportedly hurled rocks, bricks and bottles at the authorities.

Local television reports showed cops chasing the wannabe concertgoers down the streets and firefighters attempting to extinguish flaming street debris. The city's Emergency Medical Service reported that a cameraman with a bleeding head was among the dozens injured.

One news report estimated that nearly 600 disorderly fans were involved in the riot.

The Stones delayed the start of the show by 20 minutes late to allow the violent skirmishes to die down.

The concert date was the second of two shows band performed in Buenos Aires, and by far the most dangerous.

Police were forced to increase their security presence Thursday after a series of minor incidents broke out during the Estones' initial performance Tuesday night.

An increased police presence was credited with making another of the band's South American gigs go off without a hitch last Saturday. More than 1.2 million fans descended upon Rio de Janeiro's Copacabana Beach, by some accounts the largest audience ever for a rock act, for a free concert--the Stones' first in Brazil since 1998. Officials said that 10,000-plus uniformed police were on hand to keep order.

"Events like this put the lie to our violent image," Rio Mayor Ana Maria Maia told Bloomberg News shortly before the concert kicked off. "This is an event of international impact that shows the city's specialty for large events and their peaceful nature."

The Rolling Stones, of course, have a history of unruly concerts dating back to the infamous Altamont Speedway concert in 1969. About 300,000 fans attended, but instead of police or professional security guards, the Stones hired Hell's Angels to patrol the grounds of the Bay Area site. The bikers violently engaged many in the crowd and at least one spectator was knifed to death.
