The festival probably will move back into Sam Boyd Stadium as well as its surrounding fields, depending on early ticket sales. Last year's attendance of 37,439 over two days was easily accommodated on the adjacent Star Nursery Field. Combining the stadium and the fields could create a capacity of more than 80,000.

Last year's festival was headlined by Tom Petty and The Killers, but "didn't have that single-strength band that could do the numbers" to put the 45,000-seat stadium back into the mix, said stadium director Daren Libonati. "We didn't have that band that could take it over the top."

The first Vegoose in 2005 averaged 36,000 people per day and had a nongaming economic impact of $30 million, but last year's impact was half that, said Pat Christensen, president of Las Vegas Events, who pursued the festival with the promoters of the annual Bonnaroo fest in Tennessee.

"I was really happy they decided to come back again," Christensen said. "I was hoping they weren't too discouraged."

The reunited Rage, which played the stadium as a U2 opening act here in 1997, is in the league to draw big numbers. However, the festival pulls heavily from the West Coast and the politicized rockers already headlined April's Coachella Valley Music and Arts Festival near Palm Springs, Calif.

Vegoose also will share Rage as a headliner of the Voodoo Music Experience in New Orleans on the same weekend.

The festival is co-produced by the promoters behind the Bonnaroo Music and Arts Festival: New York-based Superfly Productions and Tennessee-based A.C. Productions.

Other acts announced Monday include Michael Franti & Spearhead, Umphrey's McGee, Thievery Corporation, STS9, Ghostface Killah & The Rhythm Roots Allstars, Blonde Redhead, Gogol Bordello, U.N.K.L.E., Ghostland Observatory, Pharoah Monch and Battles.

Two-day tickets are $150 and go on sale at 10 a.m. Saturday through www.vegoose.com and unlvtickets.com and at physical outlets for unlvtickets.com including the Thomas & Mack Center box office. Single-day sales may be offered later.
