wow still record stores in iowa city? that's a hopeful sign.. dope jams has fairly complete backstock for labels like planet e and basic channel, sound sig, kdj, even loads of old CR records, it's good. there is very very little garbage in there, and they also have a nice disco, soul, jazz, and hiphop selection. they do not have a broad selection of all the new-newest releases though, it's pretty slim in that regard, but they pick up good stuff.
i have never been to other music. i am not sure why.... other recommends from me would be turntable lab and defffinitely a-1, which is like 2 blocks from tt lab. a-1 is the sister store of the thing (legendary digging spot), they get first pick from any new record collections they acquire...unless you're a super bargain-hunter i would skip the thing and check out the rare goodies at a-1. if you are up for digging for a whole day for super-bargain gems among 100,000 records, hit the thing. you might not find any detroit techno there after digging for 12 hours, but it's something to behold, anyways. jt
