The best moments on No Worry No Mind, the debut EP from Brooklyn post-punk trio B Boys, marry the surreal with the everyday. Witness "Other Head," which opens with its narrator sprouting a second noggin ("I've got something growing out my neck!"), only to find him or her idling in a check cashing line moments later.

The best moments on No Worry No Mind, the debut EP from Brooklyn post-punk trio B Boys, marry the surreal with the everyday. Witness "Other Head," which opens with its narrator sprouting a second noggin ("I've got something growing out my neck!"), only to find him or her idling in a check cashing line moments later.

According to singer/guitarist Britton Walker, who shares vocal duties with bassist Brendon Avalos, this mixture of the absurd and the ordinary reflects both an admission that real-life can be unnervingly bizarre ("Sometimes it does feel hard to tell what is genuine and what is not," he said) and the difficulty of writing about abstract concepts with absolute certainty.

"When I'm starting to write, it's something that's personal, but it's also experiences and thoughts and feelings people share that are generally hard to describe," said Walker, 29, who joins his bandmates for a concert at the Summit on Monday, May 9 (drummer Andrew Kerr rounds out the lineup). "How do you describe anxiety? It's hard to understand that feeling, which is what makes it so unsettling in the first place."

The music can be similarly unsettled, building on nervy, high-tension guitars that, at times, call to mind the likes of Parquet Courts (a band B Boys is scheduled to open for on a handful of coming tour dates). It's also a sound that's consistently changing, owing in part to the musicians' collective desire to refrain from lapsing into stasis. "Never find out what ordinary means," the band barks on the twitchy "Nevah," a line redolent of its refuse-to-stay-the-course attitude.

"I don't think anyone should consider themselves ordinary. We should all try to live extraordinary lives, right?" said Walker. "There are no boundaries within the band. I think anything going forward will be different from what preceded it [because] we're still finding more of ourselves, and we still have in our minds that we're going to do whatever it is we want to do. We might do something extra different just to not meet an expectation."

Growing up, Walker moved frequently due to his father's naval career, logging time in diverse locales like Texas, Hawaii and Connecticut. Though not from a musical family, the singer was drawn to guitar from an early age, first acquiring one at eight years old after his parents returned home to find him attempting to play Metallica covers on a violin. "I think at that point they were like, 'This kid needs a guitar,'" he said.

In the years since, Walker's skillset has improved considerably, though he still refrains from immersing himself too heavily in study in order to preserve a more original guitar sound.

"I try not to learn anything too specific about music theory because I want to have my own style and my own playing come out," he said. "I didn't listen to music for a large part of my life just to keep my guitar playing and songwriting more natural. That's how the songs I've written come to be. Sometimes just putting your hand in a weird position and seeing what comes out. [The guitar] can still surprise me all the time."
