California's genre-bending art-hop outfit Why? bring their deranged, poetic pop to Chicago in support of their latest album, Alopecia. Frontman Yoni Wolf spits wordy diatribes that fall somewhere between his Anticon Records backpacker brethren and a Malkmus drawl, while his band follow suit, shifting chameleon-like between hip-hop panoramas and indie-pop jangle. Alopecia is a masterpiece of hybrid hip-hop, full of complex, upsetting songs — the sort of stuff that gives pigeonhole-happy music journalists nightmares. For the rest of us, it's a dark, bittersweet delight.
