#7 Music Festival
Manchester, Tennessee
The four-day concert, owned and produced by Superfly Presents, continues to pioneer digital and social media elements, juxtaposing them against the rural grounds in southern Tennessee.

Next: June 2014

#8 Music Festival
Miami
The electronic music festival celebrated its 15th anniversary this year by expanding to two consecutive weekends, which boosted attendance from 200,000 to 330,000. The new two-weekend format is one embraced by several music fests, including Coachella and Austin City Limits, and music insiders have wondered if Lollapalooza will follow suit. Ultra, which relocated to Bayfront Park in 2012, is still waiting approval from city officials for its second weekend next year. The move is no sure thing: After a city commissioner tried to block this year’s additional weekend, the festival had to pay $500,000 for increased security. Next: March 28-30, 2014

#9 Music Festival
