Post-rock can be magnificent and moving; post-rock can be repetitive and boring. A. Armada is a band deftly avoiding what can weigh down the sort of music they play.

“I think that there are bands that overthink things and some that underthink things,” said guitarist Matt Nelson. “Neither one is necessarily a bad thing … but even though music can sound complicated, it’s really not, it’s all very simple.”

Nelson’s experiences working at The Caledonia have certainly influenced his music-making decisions in the band and his opinions about music in general. Seeing trends in new and upcoming acts in Athens for two and a half year allow Nelson to differentiate between what is novel and what has become convention and funnel this back to his band.

Perhaps what is so striking about A. Armada is that every piece of the band is solid and well-constructed, remaining distinct and interesting without becoming muddled in noise.

Jeremy Harbin, the band’s drummer, also commented on the state of post-rock as an established genre. This is strange when considering the idea of post-rock as one of removing the rock ‘n’ roll tropes that frame so much of pop music today.

“You know, I listen to all kinds of music, we’re all listening to different things,” he said. “But 80 percent of it is bullshit, even the stuff that the blogs or Pitchfork is going to tell you about. I’ve kind of stopped listening to new stuff.”

This isn’t music that is made to fit, and it isn’t made to be different, either, which is kind of the point. It is just made as a place for you to inhabit.

Nor is the arrangement of the band’s music too technical or trying to stay in one spot to delineate one song.

“It’s more with the mood of things, just following the changing of moods in songs,” Nelson said. “It’s never written like, ‘let’s flip it and go to a minor chord,’ and I don’t want to necessarily say they write themselves, but they kind of do.”

Nelson also plays with bassist Bryant Williamson in math-rock band Cinemechanica, where the two switch instruments and trade their wandering melodies for hard guitar riffs.

“They [Cinemechanica] kind of steamroll you. We like to caress your face a little bit,” Nelson said. “And when A. Armada plays, I think a lot of people are just deer in the headlights. A lot of people just take it in.”

For a band whose primary output is jammy, wandering soundscapes without lyrics, leading listeners on into oblivion, the band has a surprisingly wide audience.

“It’s a fine line when you’re playing late,” Harbin said, “Are some of the frat-types mocking you or really into you, like these guys at our AthFest show. But you know, I think that usually they really do like it.”
