On their new album, "Days of Abandon," Brooklyn indie-pop stars The Pains of Being Pure at Heart have traded the sturm-und-drang guitar noise of the band's last record for a shining, crisp sound that reveals the peppiness and brightness of the latest songs. Fear of Men and Ablebody open the show at the Rock and Roll Hotel.

Heartbreak is a horrible thing. Just about the only good that comes out of it is the inspiration for albums like Deer Tick's "Negativity." Piano-driven laments punctuated by soulful horns, upbeat alternative rock songs, swaggering "let's stay together" country rock -- this is an album that covers a lot of sonic and emotional territory. Langhorne Slim and the Law and the District are first on the bill at the Black Cat.

If you're in the mood to dance to electronic music, there are two terrific options tonight: new-school drum'n'bass leaders Ed Rush and Optical bring their hard-charging jungle sound to Ultrabar for an 18-and-over show. Tickets are $12 in advance, or $15 at the door. Up at U Street Music Hall, Simian Mobile Disco offers a dancefloor-ready set of funky house, bubbling krautrock and blippy techno. Don't expect the big-beat electro that made them popular (ie "Hustler"), but the more intricate sounds from the English duo's recent album and 12-inch singles.

Also tonight: Original Bad Boy Records girl group Total performs at a tribute to the Notorious B.I.G. at the Howard Theatre. (You may remember that they sang the hook on Biggie's breakout hit "Juicy.") Read more about that show in our Nightlife Agenda picks of the week.
