Cost: $7 ($5 with postcard/any ad); $25 pre-admission Saturday 8-10 a.m.

Organizer: Chicago Independent Radio Project

What to expect: Several rooms of the Pulaski Park Fieldhouse will be jam-packed with rare vinyl, CDs, DVDs, posters, crafts and independent publications. There will also be an expanded musical lineup for your listening pleasure.

Why to go: For music nerds, no explanation is needed. But even if you're not in a crate-digging mood, the solid music roster should entice you to the fair; The Soul Rebel's Chic-A-Go-Go Dance Party (filmed for TV!) on Saturday and Yea Big & Kid Static on Sunday are both worth the price of admission.

Additional info: That pre-admission fee gets you unlimited access all weekend long, in addition to the early-bird period on Saturday. So far, dealers include legendary rock label Touch & Go and St. Louis' Atalantic Poster. The full music lineup:
