Previews by August Brown Mirah The K Records staple has quietly amassed one of the most endearing bodies of work in the lo-fi singer-songwriter scene of late. Her pristine alto is the centerpiece, but her songs are spiked with punkish rebellion. Bootleg Theater, 2220 Beverly Blvd., L.A. Today, 9 p.m. $14. (213) 389-3856.

Free Energy / Useless Keys Disco was supposed to be a rebuttal of classic rock, but leave it to LCD Soundsystem’s James Murphy to buck the conventional wisdom and produce this gang of swaggering Philadelphians’ debut. They hold court with the gloomier but equally throttling Useless Keys. The Echo, 1822 Sunset Blvd., Echo Park. Mon., 8 p.m. Free. (213) 413-8200.

The Strange Boys This cryptic Texas band’s sound is rooted in the lo-fi surf-garage scrim all the cool kids are into these days, but they skulk about onstage like they’ve seen a ghost in the bottom of a sack of mescaline. The Echo, 1822 Sunset Blvd., Echo Park. Fri., 8:30 p.m. $10. (213) 413-8200.

Dirty Projectors The band had a banner year in ’09 with “Bitte Orca,” but now David Longstreth and his trio of sirens will reprise his early album “The Getty Address” with guest contributions from the L.A. Phil and Alarm Will Sound.Walt Disney Concert Hall, 111 S. Grand Ave., L.A. Sat., 8 p.m. $39.75-$68.75. (323) 850-2000.
