Throngs of dance music fans are expected to fill Las Vegas this weekend as the three-day Electric Daisy Carnival returns tonight.

Festival organizer Insomniac expects about 140,000 people to crowd the Las Vegas Motor Speedway each day.

This is the music festival's fifth year in Las Vegas. The event includes a lengthy lineup of DJs performing on elaborate stages amid a carnival-like setting of rides, pyrotechnic displays and art installations.

The event starts at 7 p.m. each night and ends at 5:30 a.m. Check back here all night for updates from the festival.
