E-music has Hallelujah Sirens, the new album from Brooklyn's Dirty on Purpose, for download in advance of its release later this month. Dirty on Purpose create great messy, hazy rock songs that balance sonic rumblings with the harmonies of keyboardist Erika Foster and drummer Doug Marvin. Definitely worth spending some time with. So hurry on over and give it a listen, and while you're there you can download their EP Sleep Late for a Better Tomorrow.
