Ultimate Classic Rock and Diffuser.fm are offering you and a guest the chance to win a pair of 4-day passes, complete with car camping privileges, to one of the year's most exciting musical events -- Mountain Jam 2013, featuring Phil Lesh & Friends, Gov't Mule and many more great bands.

It all takes place June 6-9 at the Hunter Mountain ski resort in Hunter, New York. Tickets are on sale now at the festival's official site. Gov't Mule guitarist and Mountain Jam co-presenter Warren Haynes explains the appeal of the festival, which he's been involved with for each of its nine years, very simply: "We cater to people that really take music seriously."

One look at the initial lineup shows how right he is. Among the artists performing in this beautiful setting you'll find Widespread Panic, Primus, Dispatch, Gary Clark Jr., Soulive with the Shady Horns, Jackie Greene, Deer Tick, ALO, Rubblebucket, the Amy Helm Band, Nicki Bluhm & The Gramblers, the Revivalists, David Wax Museum and Simo.

In addition, a host of local food trucks will set up shop on the grounds, sparing you from the usual concert venue pizza and burgers monotony. Also, for the first time, special car-side camping — part of our prize package — allows you to drive right to your camping spot, no hauling of gear required.

Sounds great, right? For your chance to win a pair of 4-day passes for Mountain Jam 2013, as well as a car-camping pass, simply follow @diffuserfm and @ultclassicrock on Twitter and re-tweet the announcement of the giveaway by noon EST on Saturday, Feb. 2, 2013.
