CHILLICOTHE — The second round of artist announcements for the 2016 Summer Camp Music Festival released Thursday promise to bring Tom Petty, The Roots and many others to central Illinois on Memorial Day weekend.

The biggest act announced, Mudcrutch, might be an unfamiliar name to some. However, it's one of Tom Petty's first bands, the precursor to Tom Petty and the Heartbreakers that includes some of that group's members in Mike Campbell and Benmont Tench. Mudcrutch had a one-off reunion in 2008 but reportedly began recording a new album last year.

"That was something that fits in with what we've done in past years with Jane's Addiction and Steve Miller Band," said Mike Armintrout, marketing director for Jay Goldberg Events. "But most importantly, it brings Mr. Tom Petty to Summer Camp."

One of the other big acts will be making its return to Summer Camp, bringing with them a much larger following this time around. The Roots played Summer Camp in 2008 when the group was mostly known as a legendary hip-hop act. Since then, the group was tabbed as the house band for "Late Night with Jimmy Fallon" and then joined him for his promotion to "The Tonight Show."

"They have gained a lot of notoriety on late night than what they had, which was already big," Armintrout said.

To further entice what is one of the substantial fan bases for the festival, an Electronic Dance Music super group composed of Big Gigantic, GRiZ and Gramatik will perform together under the moniker Big Grizmatik.

"We had this project at the festival two or three years ago, but it was not fully fleshed out yet," Armintrout said. "All three of them would be headliners on their own and have been for us. It's very much a live electronic super group."

Other acts announced include Ani DiFranco, Excision, George Clinton & P-Funk, Cherub, Louis the Child, Lotus, Fishbone, Lil Dicky, Slow Magic, Sam Feldt and many more.

"We have a number of acts in this announcement for our diehards and a number of them that are fresh and new," Armintrout said.

Three-day tickets are currently on sale for $199.50 at www.summercampfestival.com or by phone at 1-800-514-ETIX.

In its 16th year, Summer Camp Music Festival will feature more than 100 artists on eight stages, including festival stalwarts moe. and Umphrey's McGee performing all three days. For more information and updates, visit www.summercampfestival.com or the Summer Camp Facebook page.
