The 35-year-old Jonsi launched his solo debut Go with the same giddy sense of joy and wonder you may remember from your first carnival -- or better, your first big pride festival. It's certainly not anything you could have expected from the ambient rocker, lead singer of the Icelandic band Sigur Ros, with the ethereal, even elfin countertenor voice and penchant for making dazzling, sprawling music with a gloomy, cloudy sheen. Go on the other hand, is much clearer and less mysterious, moving at a brisker clip. And he plans to give it a full cinematic treatment in concert, with projected images responding to the music. Tickets remain for the concert Tuesday, Nov. 9, doors at 7 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $35. Call 202-265-0930 or visit 930.com.
