O.A.R. returns to Penn’s Peak Sunday at 8 p.m.

During the course of its two decades of making records, O.A.R. — lead singer and primary songwriter Marc Roberge, drummer Chris Culos, guitarist Richard On, bassist Benj Gershman and saxophonist/guitarist Jerry DePizzo — has created and maintained a sort of a parallel universe.

In effect hiding in plain sight from the world outside, the band fills arenas and amphitheaters as it crafts and releases relatable songs with big pop hooks, all of this activity going down completely apart from the mainstream.

Within this universe, these songs are bona fide hits, and the band members are superstars.

“People like being part of what we are doing, because we exist and we succeed within our own community,” Roberge says.

“We have no desire to exist or succeed by someone else’s standards. We just want to provide for our families and give them every opportunity, and do that by playing shows and making music.”

“XX,” the band’s latest CD, is neither a career culmination nor a conventional greatest-hits album; rather, it’s a sizing up, a series of aural snapshots on a continuing journey.

Roberge views O.A.R.’s evolution as a series of steppingstones — he refers to this zigzagging movement as “island-hopping” — and each of the songs on “XX” represents a moment of significance for the band members and for their devoted fans.

If there’s a thread that runs through this music — from the band’s humble beginnings to its present hard-earned status, it’s affirmation and uplift.

This expansive humanistic impulse, which remains a central aspect of the band’s appeal to its legion of fans, “comes from a few different places,” Roberge says.

This communal process of therapy/exorcism/ecstasy animates the songs and performances hand-picked by the band members to represent the magical world they first envisioned as teenagers and have inhabited ever since.

Some dreams die hard. And some dreams are built to last.
