COACHELLA VALLEY (KTLA) -- More than 80,000 music lovers braved the heat over the weekend at the Coachella Valley Music Festival.

The three-day concert was held at the Empire Polo Club in Indio, and featured performances by 120 music acts spread across six stages.

Headliners included Kanye West, Kings of Leon and Arcade Fire.

There was a change in the overall tone of the festival, with more light shows that appealed to the younger generation in the crowd.

Twitter and Facebook also helped bring in a younger and more international crowd this year.

This year's event sold out in a record six days. Tickets ran around $300 per person.

Organizers had a tight rein on gate crashers and transportation problems.

About 45 people were arrested, most of them for drug use, public intoxication and trespassing, according to police.

Concertgoers had to cope with some very hot temperatures.

Saturday's midday temperature at the concert was 90 degrees, lower than the projected 100.

Downtown Los Angeles was 91 degrees Saturday, a record high for the area, which reached 90 degrees in 1999.

Sunday temperatures were milder around the Southland, with highs in the 70s and 80s in most areas as a breeze moved in.

Clouds were expected to move in late Sunday with a chance of showers Monday.
