Corpus of AAVE?

Dear colleagues,

I am looking for a corpus of African American Vernacular English (I'm
interested in asking questions about syntax so phonetic detail is not
particularly important).  I've looked in the usual places without any
luck.  Does such a thing exist?

Thank you,
Chris Dyer
