Pop-rock band Mayday Parade will continue celebrating its 20th anniversary with a show Nov. 29 at Mohegan Sun Arena at Casey Plaza, Highland Park Boulevard, Wilkes-Barre.

The group — touring with All Time Low, Four Year Strong and The Paradox — released the eight-track “Sad” in October. The set, the second in a trilogy, followed “Sweet,” which arrived in April.

“The original concept for the three-part album happened one night while we were in the studio,” said bassist Jeremy Lenzo, who also provides backing and co-lead vocals. “Originally, we were just going to do one release. One thing led to another and we decided to do something bigger.”

Earlier this year, Mayday Parade released videos for “Sweet” tracks “By the Way” and “Who’s Laughing Now,” plus “Sad” track “Under My Sweater.”

The band, whose music also encompasses punk, alternative rock and emo, plans to release the trilogy’s final part in early 2026. The trilogy follows the band’s seventh studio set, out in 2021.

Rounding out the lineup: Derek Sanders, lead vocals, piano and extra guitar; Alex Garcia, lead guitar; Brooks Betts, rhythm guitar; and Jake Bundrick, drums/percussion, plus backing and co-lead vocals.

Lenzo, born and raised right outside of Tallahassee in the small town Waukeenah, credits his father as a musical influence. Lenzo decided to learn guitar after seeing his dad play every morning before school.

“He showed me a few chords, and I practiced those for a while. I ended up going to Walmart, bought a poster that showed the different chord positions, and kept learning from there.”

Around that time, Lenzo started getting into pop-punk. Favorite acts influencing his musical direction include Saves the Day and The Get Up Kids, Lenzo’s “gateway bands into the pop punk/emo scene.”

Mayday Parade formed in 2005 in Tallahassee, Florida, following the merger of two local bands. Lenzo and Garcia, who earlier as high school mates were in the group Aventine Hill, played in Defining Moment and Kid Named Chicago, respectively.

The groups, which practiced in close proximity to each other, often hung out together. At some point, Lenzo said, “we had a discussion with some people who wanted to try and make this a career.”

During the first trial-band practice, “we ended up writing ‘Three Cheers for Five Years,’ still a popular song in our catalog.” The track appeared on the 2006 EP “Tales Told By Dead Friends,” copies of which Mayday Parade sold while wandering around venue parking lots during the 2006 Warped Tour.

Guitarist Jason Lancaster, shortly after the band recorded its full-length debut album, left the band.

“It was difficult when we lost Jason midway through our tour,” Lenzo said. “We had to figure out how to proceed as a five-piece,” switching around guitar parts and delegating the vocals Lancaster sang.

“Myself and Jake had to start singing,” Lenzo said, “and I guarantee it wasn’t good at the time.”

Topping 500,000 in domestic sales, Mayday Parade’s debut album “A Lesson in Romantics,” featured tracks such as “Jamie All Over,” “Miserable at Best” and “When I Get Home, You’re So Dead.”

Mayday Parade’s discography includes six entries on The Billboard 200 albums chart, including 2013’s top 10 “Monsters in the Closet” and 2015’s “Black Lines.” The latter ranks among Lenzo’s favorites.

“It’s not a fan favorite, as it was a departure from our normal sound, but it was fun to make,” Lenzo said. “We went into it knowing what type of music we were aiming to create. It was a cool process.”

Mayday Parade’s members, who live in different states, mostly write individually and bring songs to the group, with members then voting on which have the most potential.

“We’ve probably been doing it like that for the past five or six albums,” said Lenzo, whose folk-rock side band with Betts, Truth or Consequence, released an EP in 2013.

Prior to Wilkes-Barre’s show — the quintet’s last before a European tour in January — Mayday Parade will play venues such as The Met in Philadelphia and New York City’s Hammerstein Ballroom. The group recently played a date in Orlando, Florida, celebrating the Vans Warped Tour’s 30th anniversary.

Having long ago marked traveling, playing music across the states and affording a tour bus off its list of aspirations, “I don’t think we ever anticipated playing across multiple continents,” Lenzo said. “Or to still be doing it after 20 years.”

The musician credits Mayday Parade’s lineup staying intact since 2007 to the fact that “we were all like-minded in what we wanted. Not to say Jason wasn’t, but he wanted to get married and settle down. We still had the drive to be on the road and keep building our name.”

Being friends since high school “and enjoying being around each other,” Lenzo said, “has helped keep us together all this time. I’ve spent a majority of my life with these guys. We’re family.”
