Men? Bands? Who needs 'em? Not urban folk/pop priestesses Pi and Emily Zuzik. Pi (née Erin Lumsley) has the sweeter pop voice, adding light hip-hop beats and funky phrasing to her material. Zuzik, with a harder-edged rock vox, sticks more to the singer-songwriter vein. Both honed their chops in everything from coffeehouses to classic-rock cover bands, and on this DIY tour they provide backup for each other. To keep costs down, the third band member doesn't even need a dinner per diem. "THE BOX," an electronic prop/visual/DJ developed by Pi, gets equal stage space, spitting out beats and the occasional smoke puff. At least we finally know what happened to that robot from Short Circuit.
