SAN BERNARDINO - Perhaps they should call it the National Hip-Hop Show.

Thousands of hip-hop fans crammed into the National Orange Show on Saturday for the Rock the Bells hip-hop festival featuring more than 40 acts.

The two-day festival continues today at noon and will feature headlining acts New York's Nas on the Rock on the Bells stage; Los Angeles' Ice Cube on the Paid Dues Stage; and Los Angeles' Xzibit on the Guerilla Union stage.

Barker didn't speak when he came out except with his drums while Yelawolf entertained the audience with his speedy rhymes.

"It's an honor to be here at Rock the Bells," Yelawolf said to a screaming crowd at the main stage.

Later, he and Barker played new songs from a collaborative effort called "Psycho White."

The festival features three different stages. This is the first time the show has taken place over two days.

Weather reached 98 degrees on Saturday, according to www.accuweather.com.

"It's hot. Too hot," said Jazmin Fields, 23, of Burbank as she stood near an oversized boom box that had large fans spray out water.

But business was good for Mariela Licon of Colton, who worked at Lino's Rico Taco booth on Saturday.

The company, which has locations in Colton and San Bernardino, had sold more than 50 asada fries as of 2:30 p.m. Saturday at $9 each.

"It's going really well," Licon, 19, said.

Lamar Calica, 30, of Vallejo said the number of acts brought different groups of people together.

"That's good," said Calica, who wore a shirt

Calica said he attended the first Rock the Bells in 2004 that featured the last appearance of Ol'Dirty Bastard performing with the Wu-Tang Clan before he died months later.

"It's now outdoors and feels more like a real festival," Calica said of the 2012 version of the event.

He added he drove from Vallejo instead of going to the Shoreline Amphitheater because of the event's history in San Bernardino.

"This is where it was born and raised," Calica said of the festival.

Alex Gonzalez, 20, of Long Beach couldn't decide which of the acts he wanted to see at the festival.

"Who am I not here to see?" he said with a grin.

But Fields said she thought the festival should be just one day instead of two.

"They put too many mainstream acts on like Tyga and 2 Chainz," Fields said. Her tastes were more underground like Salt-N-Pepa, Common, Zion-I, Grouch and Eligh, she said.

The crowd, primarily young with nearly every racial group represented, wore a colorful mix of tattoos, basketball jerseys, tank tops, sneakers and hats.
