For some music fans, summer doesn't truly arrive until the throngs descend upon a 700-acre farm in Manchester, Tenn., for Bonnaroo. 

The annual four-day music and arts festival, now celebrating its 10th year, plays host to some of the hottest acts in music while also striving to be a leader in sustainable entertainment. This past fall, the festival received its fourth A Greener Festival award, the most for any U.S. event as recognized by the international standard for environmentally efficient music festivals.

"We take a lot of pride in being ahead of the curve in terms of environmental innovation on site," says festival organizer Rich Goodstone. "But there's a larger picture to look at here, where we're making a difference in the lives of the thousands who come to Bonnaroo every year."

Last year's efforts (organizers work hard to trump the previous year's results), resulted in more than 60 percent of waste being diverted from landfills. That works out to around 101 tons of commingled recycling, 23 tons of cardboard, 21 tons of scrap metal, 45 tons compostable material, and 5 tons of cooking oil — along with offsetting about 900 metric tons of C02.

This year, Bonnaroo added a fully paperless ticketing system and is promoting a partnership with the Urban Land Scouts — who will award badges to patrons for green actions on site. Besides extensive recycling, composting, and renewable energy use, the festival will once again feature the Planet Roo village, an area dedicated to preserving the environment and promoting healthy living.

More than 125 bands and more than 20 comedians performing on 13 stages over four days will entertain the masses with acts like Eminem, Lil Wayne, Buffalo Springfield and Arcade Fire serving as the big headliners. More than 130,000 people attended last year. 

If you couldn't score a $200 or higher ticket early, you can still catch the action virtually with a live stream on Vevo starting June 11. Check out a full list of the scheduled acts below or check out the official site here
