Rick Springfield, Wang Chung, more pour on the music of the '80s '90s and 2000s

Nostalgia is a strong drug, and it seems to be the one that almost everyone is on these days. The concert industry thrives on nostalgia by putting together package tours zeroing in on one specific demographic.

This summer there are three-decade themed tours hitting Long Island highlighting the '80s, the '90s and the 2000s for the Generation X and Millennial crowds.

'I Want My '80s Tour'

The '80s was a massive and extremely diverse decade for pop music and the bill for the “I Want My 80s Tour,” which comes to Flagstar at Westbury Music Fair on July 9, proves it. Led by Rick Springfield, the show also features pop balladeer John Waite, new wave duo Wang Chung and soul singer Paul Young.

“This is an all-hits show. We pack the set with wall-to-wall songs everybody knows,” Springfield, 75, says. “My song ‘Jessie’s Girl’ took on a life of its own. If I knew why, I’d write 20 of them.”

Young, who had popular tunes such as “Every Time You Go Away,” “Come Back and Stay” and “What Becomes of the Brokenhearted,” vocally evokes old-time singers like Joe Tex, Otis Redding and Chuck Jackson.

“In the '80s, it was like anything goes,” Young, 69. says. “You could be influenced by anything you wanted. The barriers were down.”

Expect to hear cuts like “Dance Hall Days” and “Everybody Have Fun Tonight” from Wang Chung.

“We still enjoy playing ‘Dance Hall Days’ live,” singer-guitarist Jack Hues, 70, says. “It’s a spine-tingling moment on stage that gives everybody a huge rush.”

WHEN | WHERE 7 p.m. July 9; Flagstar at Westbury Music Fair, 960 Brush Hollow Rd.

'Pop 2000 Tour'

At the turn of the century, the Billboard charts were packed with boy bands and the “Pop 2000 Tour,” which comes to the Patchogue Theatre for the Performing Arts on July 13, reflects that time. Spend the evening with O-Town, BBMAK, Ryan Cabrera, LFO and host Chris Kirkpatrick of *NSYNC.
“This is a trip down memory lane when MTV’s 'TRL [Total Request Live]' was king, there were no cellphones and we all used wind-up cameras,” says Kirkpatrick, 53, who performs *NSYNC hits with O-Town. “There was so much innocence, just fun pop music. You get to go back and relive your childhood.”

Cabrera will play his hits “True,” “Shine On” and “On the Way Down.”

“I just want my music to be honest regardless of what people think is popular,” says Cabrera, 42. “I try to write what I’m feeling in the moment. That’s where my best material comes from.”

The LFO catalog gets resurrected by sole surviving member Brad Fischetti, who breaks out singles “Girl on TV,” “West Side Story,” “Every Other Time” and the Top 5 hit, “Summer Girls.”

“I always start the song by saying, ‘As the late Rich Cronin would say, “Where the summer girls at?” ' The crowd sings every single word with us,” says Fischetti, 49, who gets some assistance from O-Town. “I miss my guys, Rich and Devin [Lima]. On stage, I do everything I can to honor them.”

WHEN | WHERE 7 p.m. July 13, Patchogue Theatre for the Performing Arts, 71 E. Main St.

'Summer Unity Tour'

When it comes to '90s rock, two bands stood out for offering introspective lyrics paired with power riffs. Live and Collective Soul are sonically different but spiritually alike as they unite with Our Lady Peace for the “Summer Unity Tour” at Northwell at Jones Beach Theater on July 31.

“Ed Roland [Collective Soul lead singer] and I get along great. When you hear the songs together with both bands, it’s a crazy show that makes for a great night for fans,” Live lead singer Ed Kowalczyk, 53, says. “I feel very fortunate to have been in the scene with alternative rock music in the '90s. It was a big change. There was a huge plethora of unique voices.”

Collective Soul is touring in support of its latest release, “Here to Eternity,” a double album featuring the hit “Mother’s Love.”

“I think there’s less angst plus we are more seasoned and comfortable with our sound. We’ve evolved spiritually and opened our minds creatively,” bassist Will Turpin, 54, says. “Our songs have become the soundtrack to people’s lives. They have memories associated with our music. It’s magical.”

WHEN | WHERE 6 p.m. July 31, Northwell at Jones Beach Theater, Wantagh
