A major country music star, a legendary blues-rock powerhouse and an over-the-top ’70s funk show lead the lineup for the 63rd annual Maine Lobster Festival, which kicks off Wednesday, Aug. 4 at Harbor Park.

On tap on Wednesday, better known as Hometown Day and featuring free admission for all, will be an afternoon concert by Bay Winds, versatile local musicians who will set the stage for the city’s annual tribute to the U.S. Coast Guard. Wednesday evening, local talent will rock the North Entertainment Tent thanks to last year’s winner of Trekkapalooza, Tastes Like Chicken, and this year’s winner, Chaos Sauce.

On Thursday, Aug. 5, two of Maine’s favorite bands will liven the evening. The main stage will play host to up-and-coming Portland band Adam & The Waxmen at 5:30 p.m. and over-the-top funk stars Motor Booty Affair at 8 p.m. There is no charge for seating, and there will be plenty of room for dancing at both shows. Scheduled for Thursday evening in the North Entertainment Tent are Celtic favorites Castlebay and the Nat Hussey Band, led by Matinicus lobsterman and sustainability advocate/songwriter Nat Hussey.

The Friday, Aug. 6 headliner is the awe-inspiring Southside Johnny & The Asbury Jukes.

“I’ve been wanting to bring this great band to the Festival for many years,” said entertainment director Chuck Kruger. “With a new album and a stellar lineup, which includes veterans of Conan O’Brien’s band on NBC, this should be an amazing show.”

Opening the Friday night bash will be the Jessica Prouty Band from the Boston area, a fast-rising group of teen musicians who will kick things off in fine fashion. The North Tent on Friday will feature fam-folk phenoms Mustard’s Retreat, a nationally acclaimed duo from Michigan who seem to arrange their summer tour to hit the festival. Vocal chorus Harborside Harmony returns as a fest favorite. New this year is the fun, fabulous, 50-something band RetroRockerz, who promise a street dance for those who live to remember and then try to forget.

“I don’t know how we do it, but we landed another major country superstar for Saturday,” said festival president Tim Carroll about Clint Black and his band on Saturday, Aug. 7. “Everyone’s pretty excited about it, that’s for sure.”

Opening for Black will be the Kelly Parker Band of Portland, a versatile country-rock group that has been making waves all over New England this year. Also on hand Saturday will be Midcoast faves the Steelin’ Thunder steel band, acoustic duo Mustard’s Retreat and the Mallett Brothers Band making their festival debut.

On Sunday, Aug. 8, the Main Stage will see the long-debated return of the Wicked Good Band, who are contractually obligated to perform their song “If you’ll be my Rockland lobster, I’ll be your Yarmouth clam …” Always popular at the festival is the Windjammer Chorus, official barbershoppers of the Midcoast; and the ubiquitous Robby Coffin returns with his combo this year to close the festival on a high note.

Festival admission is free on Wednesday, and is $8 for adults Thursday through Sunday. Tickets for seats for the Southside Johnny show are $20 and include festival admission; Clint Black seats are $35 and also include festival admission.
