At the quarter of life, humans often face existential crises, directional anxiety and stress of breaking into onset adulthood.

Maybe Will Toledo has experienced some of that. Or maybe not. The Car Seat Headrest frontman has been pretty busy. In May, he released his 13th album. He’s 24.

In five years, the brain behind the indie rock group pumped out album after album on Bandcamp, gained a rabid following and was picked up by Matador in 2015 for his 13th release, “Teens of Denial.” Now living in Seattle with a full band (he found drummer Andrew Katz on Craigslist), a bigger budget, a proper studio and producer Steve Fisk, Toledo is soaring in his mid-20s — a constructive path many twenty-somethings only daydream of (with “Teens of Denial” on repeat).

“I don’t know if I was shocked,” Toledo said, of his fast-forward to a record deal. “It was something I’d been working towards for a while. It was gratifying how quickly everything changed.

“I went from feeling fairly frustrated with where I was to things were pretty much better than I could have expected by the turn of this year.”

The loose epic of “Teens of Denial” follows Toledo’s melancholic alter-ego, Joe, through a barrage of good and bad trips, searching for an identity, existentialism and responsibility.

Car Seat Headrest will perform at the Fox Theatre on Monday — Halloween night. At the rate the band’s popularity is swelling, a night to catch it at the intimate venue may be a coveted check-mark some day.

“It’s about having the right set for the right place right now, especially with the ‘Teens of Denial’ material, and it’s all mid-level venues — or the smaller venues in the city which are still a more appropriate place for us to bring the set,” Toledo said. “Once we start going to that higher level where we have to make some alterations to our set and to our performance and add more members, more crew — so it’s good to be at a spot where we’re able to play the show without worrying too much about that.”

Toledo said the transition from his signature lo-fi, DIY ethos to a major label has been fairly smooth, noting that Matador is generous when it comes to artists’ preservation of an artistic vision. His single “Drunk Drivers/Killer Whales” was in need of a cut for the album version, so Matador let him do his thing.

“That’s something that I’m not necessarily used to, trying to fit everything into a three-and-a-half minute time frame,” Toledo said. “It’s pretty difficult to pare it down like that, but I think we’ve got a version that I’m happy with.”

He said there is plenty of pressure involved, “but it’s just about taking them as a challenge and not letting it interfere with my artistic integrity.”

And like his quarter-life peers, Toledo said he does suffer from generalized anxiety and emotional angst, which he manages by filling mind voids with his music.

“I don’t rest easily in general,” he said. “I think that as I get older, maybe it’ll get easier, but now I need to be engaged on this level. If I have more free time, I’m not necessarily relaxing, I’m just getting anxious … So it’s good to do something every day. Have something to do every day and feel like I’m accomplishing anything.”

With “Teens of Denial” already hitting mid-year best-of album lists and the band deep into album 14, he seems to have plenty to keep him occupied.

“It’s the first time I’ve really been able to call music my life and my living,” he said. “I’m mostly just really pleased with that.”

“(Lo-fi) was one phase of my artistic output,” Toledo said. “I’m moving past it now — well, moving past the lo-fi aspect of it at least, not necessarily the DIY. This month I’ve actually been doing a lot of mixing myself. I take the lessons that I learned from that era and trying to bring it into a more commercial, more easily accessible production style. And I’m kind of happy with the results so far. The things I’m working on definitely don’t sound lo-fi, but they still definitely got a lot of distinct character to them, which is good. I wouldn’t want to have had that lo-fi aesthetic my whole career, that was just not knowing how to get better at it, basically. Having learned some lessons over the past year and just sort of listen intently to what is going on in other music, I was able to jump up a level I think. And I’m happy and excited to see what comes next.”

What’s next?

“We started recording, I’m going to be mixing for the first half of December for our next bigger projects,” Toledo said. “Right now it’s just all raw tracks but I think it captures what is good about us right now — which is that we’re a pretty tight, live band. We’re finally able to get into the studio and lay stuff down fairly easily. I’m hoping that will be finished by next year.
