Pop music: Dum Dum Girls at the Echo

If there’s a sound of summer in L.A. indie in 2010, it’s the kind of scuzzed-out, Spector-addled, two-minute pop bliss that the Dum Dum Girls ply. Their debut full-length, “I Will Be,” is like bag of candy dropped in broken glass — shredded but sweet, delicious but disenchanted. The Echo, 1822 Sunset Blvd., Echo Park. 8:30 p.m. Thurs. $12. (213) 413-8200.
