I haven’t found any archives yet, maybe you all would have better luck than me, but I know there has to be some good stuff.
The radio station in Chicago to check is WVON. Obama was a frequent guest and HOST on this station.
WVON - The Talk of Chicago - provides an interactive forum for the African- American community to discuss current, social, economic, and political issues.

wow, if WVON is oriented specifically toward the “African-American community” and Obama appeared as both host and guest then there is a much greater chance that he spouted Jeremiah Wright kinds of rants when he thought he was “safe” with a more limited audience of brothers and sisters.....
There could be gold there if anyone can find recordings......
