Prepare to be amazed by Decades Rewind.
"It's a theatrical concert with music from the '60s, '70s and '80s," says Decades Entertainment cofounder Peter Gatti. "We start in the '80s and rewind back to the '60s."
About 60 songs are presented per concert. So many songs are presented in one evening that they're sung in medleys.
"There are genre-specific medleys to era-specific medleys," Gatti says. "There are 14 people on stage, including an eight-piece band with a horn section."
Three onstage video screens show footage from the era the songs are representing.
"It's American culture, including Woodstock and Vietnam footage," Gatti says. "Last, but certainly not least, there are 100 costume changes that include anything genre-specific to era-specific. It's an unstoppable party/concert that is part theater and part musical."
Not one recorded track is used for the music.
"It's all live," Gatti says. "It's very high energy and two hours of fun and more fun."
Gatti, the show's keyboardist, co-founded "Decades Rewind" with Mark Blinkhorn, who is the show's drummer.
"We were playing in a cover band together," Gatti says. "On a break, we started talking about concert playing.
"We started writing down ideas and I took them to the studio I have in Tampa, Fla. We were recruiting talent.
"The next thing we know, we've visited 19 states and 50 cities," he says. "It's just something we wanted to do late in life."
All types of music from the '60s, '70s and '80s are played during the show.
"In our opinion, those are the best three decades of music," Gatti says. "We have so many songs to choose from, so it is challenging.
"Most people know every word in every song," he says. "We hear from people all the time that the show was the most fun they'd had in years. They even have tears in their eyes."
Audience members aren't just Baby Boomers.
"We literally have kids in their 20s there who love it," Gatti says. "Some songs are classics, like Janis Joplin, Jimmy Hendrx, The Doors, so even the Millennials know the songs.
"We've had people in their 80s who love the show. It's not a typical performance.
"We had one woman there with her husband on his 70th birthday," Gatti says. "He didn't want to go, but he said, 'I haven't had so much fun in 30 years.' We have 10-year-olds dancing in the aisles."
The show is not typical in any way.
"The things we try are probably different than anything out there," Gatti says. "It's more fun than you can ever imagine, like a party. For two hours, they can shut down the world.
"It's a concert, dance party and theatrical performance all wrapped into one night of singing, dancing and being transported back in time," he says. "You relive your life's best memories through music and video in a night of fun and nostalgia."
