If your band is labeled “post-hardcore,” but your new album displays a sound that’s progressing away from that place, what do you become? Hopefully, something better, even if that something isn’t easily described. And that is where These Arms Are Snakes find themselves with the release of Tail Swallower and Dove, the band’s third full studio effort. How this new mesh of pump organs and screamed lyrical threats will translate live is anyone’s guess, but the general assumption is that it’s going to be face meltingly radical. Supporting TAAS is Trap Them, catalyzed from a European tour of small venues that greeted the band with sold-out performances and roof-raising encores, as well as Seattle’s own Narrows. All ages.
