Tickets for two-day event, which is scheduled to take place Oct. 28-29 at Sam Boyd Stadium, go on sale Aug. 19 via the Vegoose website.

To coincide with the festival proper, organizers are also coordinating Vegoose at Night, a series of yet-to-be-announced nighttime concerts set to take place Oct. 27-Oct. 31 at venues throughout Las Vegas.

Vegoose is produced by Superfly Productions and A.C. Entertainment, creators of the annual Bonnaroo Music and Arts Festival.

"We are busy preparing for another great party," Rick Farman of Superfly said in a statement. "Last year proved that Vegas, Halloween, and an amazing collection of bands set in a beautiful environment is a magical combination."
