Bonnaroo Music and Arts Festival returned to Manchester, TN, this year to celebrate its 15th anniversary with headliners Pearl Jam, LCD Soundsystem and Dead & Company, among many others, but the festival’s ticket sales dropped off in 2016 to an all-time low of 45,537, The Tennessean reports.

According to the paper, this year’s ticket sales constituted a decline of 28,156 tickets sold from 2015. It was also a 46% drop from 2011, when the festival hit an all-time high of tickets sold. (The festival’s 2011 headliners were Eminem, Arcade Fire and Widespread Panic.) Bonnaroo doesn’t publicly release their ticket numbers, but The Tennessean took the public records of the festival’s payout to the Coffee County government, which gets a flat payment and $3 per ticket sold, and figured out this year’s income. They calculate that the festival experienced a loss of $9.07 million in revenue as compared to last year.

The drop off comes on the heels of Live Nation’s purchase of a controlling interest in Bonnaroo, which took place just before last year’s event and helped the festival install more infrastructure at The Farm like new permanent toilets and showers. Suggested reasons for the lack of ticket sales have ranged from lack of big-draw headliners to the ever-rising amount of music festivals around the country.

At the end of this year’s festival, Bonnaroo posted a statement addressing the low ticket sales, saying, “For the past 15 years we’ve been extremely fortunate to have over a million fans share the Bonnaroo experience with us. While our attendance is slightly lower this year, the Bonnaroo community is as vibrant as ever and excited about celebrating this milestone year on The Farm.”
