You could call “Watching it All Fall Apart” Fruition’s rock album.

Along with companion EP “Fire,” recorded during the same sessions with producer Tucker Martine (My Morning Jacket, The Decemberists), the album is a concentrated effort to capture the once primarily acoustic band’s raucous live show, according to interviews and promotional material. And there’s plenty of rocking to be had on the fuzzed-out crunch of “I’ll Never Sing Your Name” or the bouncing ’60s pop of “Turn to Dust.”

But there’s also “I Should Be (on Top of the World),” the album’s five-minute centerpiece. As the five-piece band lays down a slinky, old-school R&B groove supplemented by sweeping strings, vocalist Mimi Naja channels soul singers such as Aretha Franklin.

“I just love playing that song,” vocalist/guitarist/keyboardist Kellen Asebroek said recently from the band’s studio in Portland (though the band is based in the city, only Asebroek lives there). “We had to, like, not play it sometimes when we’re touring, just because we all love playing it so much that we end up playing it every single night. It’s like, come on, give it a rest, it’ll be OK; we’re just gonna miss it for a night.”

The song showcases the sonic freedom Asebroek and the rest of the band, which returns to the Domino Room with fellow Portland band Yak Attack on Thursday, have reveled in for the last few years.

“That’s the thing: We have all those different sounds, and we’re capable of all these different styles,” Asebroek said, “but it all still sounds like Fruition, thank goodness. There’s a lot of bands that can do the same thing and play anything, but it comes across maybe kind of jumbled or just not cohesive, which is another place that having a producer like Tucker Martine really shines.”

For a band that came up busking on street corners between gigs on tours, the shift into more electric realms could have been jarring. But the quintet — Asebroek, Naja, vocalist/lead guitarist Jay Cobb Anderson, bassist Jeff Leonard and drummer Tyler Thompson — began expanding its sound on its 2016 album, “Labor of Love.”

“I think that for the longest time we were having trouble capturing our essence, and so much of what our essence was was developed through playing on the street and trying to catch all the tension with these harmonies and this live energy,” Asebroek said. “It’s hard to capture (that) in the studio. That’s the only reason that there was ever a difference between the records and the live shows.”

When Fruition formed a decade ago, its acoustic instrumentation — at the time heavily featuring mandolin and banjo — made it a fit with the “jamgrass” and festival scenes. But even on earlier albums such as “It Won’t Be Long” and “Just One of Them Nights,” the band focused on harmonies and concise songwriting, drawing heavy influence from The Beatles, as opposed to lengthy jams.

“The bluegrass world embraced us. Even if they came to a show and were like, ‘This ain’t bluegrass, but I like it,’ that’s fine,” Asebroek said. “And then I think the jam world embraced us because maybe we’re a breath of fresh air. When you’re seeing bands that play in a 75-minute set with only five songs because they’re jamming it out — we have no songs over five minutes. I’m not in any way talking negatively about jamming or jam bands, but I think that having shorter-format songs — catchy, poppy-ish, hooky, song songs — I think that that’s refreshing whatever scene you’re in.”

After working with Martine, the band will go back to its do-it-yourself roots for its next batch of recordings, which could be released digitally rather than as a traditional album. It’s early in the process — when he spoke with GO! Magazine, Asebroek was between takes on the first song — but the band’s members have a backlog of material written.

“It seems like everyone is writing stuff that’s a little farther outside the box but a little more honed in at the same time,” Asebroek said. “I’ve been writing almost 100 percent (of my) songs on piano these days instead of guitar. I just saw Elton John a few weeks ago too, so I’m all just inspired and fired up by that. We’re just trying to make timeless sounds. I think that’s always been our goal and part of our allure for people, is we’re trying to make songs that will stand the test of time.”
