There’s certainly opportunity for wide success in a niche that unplugs PJ Harvey and Janis Joplin and splits the difference, going for bone-cold, desolate imagery of young woman as toothless wizened forest hag with a smartphone plan. Mostly this is acoustic guitar strumming beneath the ragged, resigned voice of Canadian 24-year-old Al Spx, as she calls herself, not being the type to give out her real name to perfect strangers such as the rest of the planet. Weird chick she is, then, it’s formally decided. I’ve never been one for weird chicks except for the ones who suddenly appear with two outs in the ninth, when the bouncers are kicking everybody out, but this weird chick I’d want to get to know simply for the fact that she appears to live Joplin’s “Mercedes Benz” every day and in every way — matter of fact, of it weren’t for the drums, “Holland” might as well be that song.  Doesn’t matter what I say anyway; she’ll be opening for either Adele or Florence and the Machine before you can say “Kim Carnes for Generation Doom.” She’ll be at the Middle East in Cambridge, Mass., on May 31.
