Corinne and Jeremiah Rosethorn, formerly of nomadic psych-folk/doom trio Mythical Beast, now reside near Coyote, N.M. They describe their new Not Not Fun-signed project, Ether Island, as “rock and roll.” And it is. But if you peer deeper into their soundscape, it’s also dark, melodic, reverberating and tinged with post-punk and soul inflections. It’s the kind of eldritch composition that could only be midwifed in a haunted country church. (And yes, there’s a hint of Lynchian disturbance in the red ants crawling around in their recordings.) Experience the art of Ether Island, along with groove-centric, left-field pop foursome YOU, Navajo queer No Wave/post-punk/surf twosome Discotays and poppy indie rock outfit Bellemah at Burt’s Tiki Lounge(313 Gold SW) on Saturday, April 12. This 21-plus gig illuminates at 10pm, and there’s no cover.
