DALLAS (CBSDFW.COM) – A North Texas teenager died last weekend while attending a rave party and concert held at Fair Park in Dallas. Now, this weekend, another big concert is coming to the venue and some are questioning how the people there will stay safe.

Witnesses shot cell phone video of the Electric Daisy Carnival, a rave party where people danced and listened to loud music. But most of those who attended that event agree that it got out of control. “I saw a lot of throwing up,” said Belinda Ramos. “I saw a lot of people passed out.”

Andrew Graf of Argyle died of a suspected drug overdose. He was only 19 years old. And 30 others at the event – most of whom were also underage – were hospitalized for drug or alcohol issues, or heat-related symptoms.

The City of Dallas issued citations to the rave’s promoter, Insomniac, for overcrowding, a charge that the promoter denies. But while the city continues to investigate that incident, another big event – the Vans Warped Tour – is taking place.

“It involves 72 bands a day,” said Vans Warped Tour founder and producer Kevin Lyman, detailing the festivities surrounding the weekend event. “We’ve got a skateboard contest. We’ve got gaming. We’ve got clothing companies.”

Organizers expect 16,000 people to attend the Vans Warped Tour, in addition to dozens of bands playing rock, pop and punk music. Free water will be provided at filling stations to keep them from falling victim to heat-related injuries. “We have a Slip N’ Slide. We have big fans. We have all kinds of fun stuff,” said Lyman. “It is hot, not a perfect scenario. That is one thing you can’t order up – the weather.”
