Wax addict has been closed for a year and a half at least.
Kstarke is my pic, but I'm biased for working there. Still, you're always gonna find something and it's become a pretty essential stop for people coming through the city. He's most likely to give you a good deal if you're spending a little money. and there's plenty to dig through (plus loads of well used cheaper bins) The firs t place to go for Chicago House, Disco and Italo.
Otherwise, there's Dusty Groove for soul, disco, hip-hop, jazz, and "world" music. There's always plenty there, but it won't be cheap unless you're lucky (and yes, things are often overlooked there) There are three Reckless Records in town, but I find most scores at the one on Broadway. Dave's will occasionally get house and Italo stuff that they put out for cheap (I just scored Cellophane's Music Colours for $5 last week). Others include: Hyde Park Records, Mr. Peabody, Hard Boiled, Old School Records, and a few others . Everyplace in the city, except a couple secret digging spots , use ebay and gemm to price things.
