Yet another noteworthy Swedish electronic-pop band, Little Dragon offers dreamy downtempo music, merging R&B, new wave and experimental pop. The Japanese-born Yukimi Nagano is the quartet's lead singer who first came to fame as a guest singer with the Swedish electronica duo Koop. Now with Little Dragon, she's appeared on tracks with Gorillaz and Raphael Saadiq and is set to work with Big Boi and DJ Shadow. The band's music can be a bit too electronically austere and emotionally cold at times, and Ritual Union starts off stronger than it ends. But the subtle sonics and twists of most tracks are captivating, and Nagano's girlish voice, often embellished with reverb and digital tricks, is always charming. Saturday, Oct. 29. Doors at 7 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $20. Call 202-265-0930 or visit 930.com.
