Just to come back on a few albums mentioned in the thread so far:
Cold World Hustlers-Cold Streets was rereleased on cd last year, apparently by E-Sic himself. It should still be pretty easy to find, at least on the internet. Fucking classic album.
Dush Tray-I'll Rather Lounge was also rereleased last year. Another favorite. You can probably still get it from
www.rapbay.com
CWH's Iceland isn't that rare in that there's always some being sold on ebay (litterally every week), but it still sells for a lot of money. They should rerelease that one. I know I'd scoop one or two in a second.
3XKrazy-Sick-O is not rare at all. I got one for about $2 two years ago. You can still get it off the Internet easily. It's dope.
Dangerous Dame-I Got What You Want ain't rare, it's on 99cents bin status. Make Room 4 Daddy is a little rarer, but not that much. Escape From The Mental Ward is a lot more.
SLM-Coming Out The Fog is not so rare. You don't have to pay that much money to get it, though probably more than your average used tape.
The first U.D.I. album is getting pretty rare. They should rerelease that shit.
Do Or Die-Falling In Love With The Game is hella rare. Another one I'd like to see rereleased.
But like somebody said, the rarest ones are probably those special request Too Short tapes. That'd be like the holy grail of old school bay rap.
