Over the last few years, artists from Timbaland to the Anti-Pop Consortium have proved that hip-hop has plenty of room left to grow without becoming something else entirely, but there's still a significant faction of the underground that believes two turntables and a microphone are all any true head will ever need. Among these folks, the fly rhymes of Evidence and Iriscience and tough cuts of Babu--also a member of the mighty DJ crew the World Famous Beat Junkies--have made heroes of LA's Dilated Peoples. On Expansion Team, the Peoples' second album for Capitol Records, they stridently celebrate DJ culture ("Dilated Junkies") and espouse the usual underground credos: stay true to yourself, resist violence but defend yourself if you must, effect change through rigorous dialogue. But they dance defensively around the issues of wealth and ambition on "Trade Money": "Yo, since last year I've accumulated more money / More beat breaks, been dressing a little less bummy / But more headaches and more pain in my stomach / On top of that I got a lot of people actin' funny," Evidence raps. "We don't love money," the chorus wanly asserts, "but we don't hate money." Thankfully, Evidence, Babu, and an impressive array of guest producers--the Alchemist, DJ Premier, Da Beatminerz, and ?uestlove--ensure that your head will nod even when you don't agree. The trio performs here with DJs representing hip-hop past (Jazzy Jay, Grand Wizard Theodore) and present (Craze, Z-Trip) in celebration of the new DJ film Scratch, segments of which will be screened between sets. Wednesday, March 13, 9 PM, House of Blues, 329 N. Dearborn; 312-923-2000 or 312-559-1212.
