East side stories are cool but they have alot of songs that I dont like on there. Art Laboe were cool like the first three ones, then after that they fell off hard. too many stupid songs on there. And oldies but goodies are more of like your "hot riding" oldies meaning they arent really what homies would bump at a bbq.
If you are into some hard to find oldies I know "Underground Oldies" available at national chains are cool, but like ESS's they have a few oldies that should have never been found. Also "LifeStyles of the slow and Low" are cool.
Your best bet is to go to a "remate" and get some oldies from there. There are some compalations that are at alot of swapmeets that are hella cool. They are "spill of Soul" and "Lost are Rare Oldies".
As you can tell I love oldies.
