This summer's Sioux Falls JazzFest is about to get bad - with some good blues and rock music.
George Thorogood and his long-time band The Destroyers are among three headliners for the 23rd annual music festival.
Gov't Mule is also making a pit-stop in South Dakota's largest city for the three-day event.
Fresh off his Grammy win for best Traditional R&B Performance, Gary Clark Jr. is also taking the main stage in July.
Sioux Falls Jazz and Blues Executive Director Robert Joyce says it's taken years to finally line up the heavy-hitting acts, and the diversity will suit the free event scheduled for July 17-19.
"We were pleased that these artists were available this year. We feel we have a very strong lineup," Joyce said.
Board members say they're floored by the talent coming this summer.
"Fabulous," Ron Houston said, board member for the Sioux Falls Jazz and Blues. "It's a great lineup. One of the best we've had over 15 years."
"The people who really miss out are the people who come for just one band. Because if you get up front and listening to some of these, it sends those shivers. It's just exciting," Board member Dave Eisland said.
