When the smoke clears from her lonely coffeehouse blues, her lo-fi’s too low, her lovely little whisper needs some whipsnapping, and “singer-songwriter” starts to sound like the slur it really is, a proper indie-pop songstress like Julie Doiron knows it’s time to get herself a backing band. And if you happen to be a passing handful of serenely experimental dudes with limited vocal ranges like the Wooden Stars, well, you let yourself be caught, chalk up the bright new addition to your constellation, and thank your lucky selves for finding the beautiful new voice. Together, you play and pray and hope against hope to elude the legacy of your indie-rock exes (Eric’s Trip, Giant Sand), make your amicable merger into a sparkly new love affair and a fine new album, and hit the road with the Brothers Creeggan. Shoegaze beneath these stars tonight at 9:30 p.m. at the Metro Cafe, 1522 14th St. NW. $10. (202) 518-7900. (Colin Bane)
