The youngest member of Hanson was only 6 when he formed a band with his two brothers.
Now, almost 20 years later, the band — which will perform Tuesday at the Intersection — is still a music machine, although this one plays a few octaves lower.
“Obviously, (on) the first record, our voices are higher, so that immediately makes people think things have evolved dramatically,” eldest brother Isaac Hanson said.
Isaac, Taylor and Zach were 11, 9 and 6 respectively when the boys, who hail from Oklahoma, joined musical forces.
While their music has evolved, the band’s sound is still the same at its core, said Isaac, 30.
The band’s first album, “Middle of Nowhere,” was released in 1997, and featured a few hits, including their best-known, can’t-get-it-out-of-your-head tune, “MMMbop.” The track landed at the top of the Billboard charts that same year.
Isaac describes the band as a blend of R&B and pop fronted by three singer/songwriters.
He said the group’s signature harmonies still provide the foundation for its music, including the latest album “Shout It Out,” released last year.
Any long-term relationship has its challenges, and the same holds true for the brothers’ long-term musical collaboration, he said. But at the end of the day, shared experience and a love for music win out.
“The creative process is actually the glue (that keeps us together),” Isaac said. “You respect that, and you appreciate it,”
For part of the “Shout It Out” tour, Hanson is allowing fans to chose which album they want the band to perform in its entirety by voting on its website, hanson.net.
“The fans get to pick the set list, or at least about 60 percent of it,” Isaac said.
He foresees his band of brothers continuing to create music together for at least another 20 years.
“We’re not qualified to do anything else,” Isaac said, laughing.
