Self-described as "The Greatest Band in the World. Possibly. Ever.," Possum Posse is bringing its brand of sardonic honky-tonk bluegrass music to the streets of Cowtown for this year's Stomp and Holler benefit concert. Tickets are on sale now for $12.

If the name rings a bell, it may be because Possum Posse is the group behind the viral and hugely popular YouTube series, "Guy on a Buffalo."

Concert-goers may bring lawn chairs but are asked to leave the coolers at home since the Saloon will be open with a cash bar.

Based in Austin, Texas, Possum Posse entertains audiences with a combination of memorable originals as well as remixed versions of old favorites.

Proceeds from the outdoor concert will support visitor and education programs at the Museum.
