Irish indie rockers Just Mustard do something really cool on their new track “Endless Deathless.” It’s a shoegaze song in a lot of ways, with bleary guitar effects everywhere. But Katie Ball’s lead vocal has a dreamy, mocking quality that reminds me of the generation of college-rockers and janglers that came just before the original shoegaze wave. The rhythm section, meanwhile, goes for a fast, busy herky-jerk attack that comes off more as OG post-punk. So we’re going with at least three different genres of underground rock here without quite lining up with any of them. I like that. I like that the song is good, too.
