I started putting together this website cataloging R. Aharon Rakeffet’s lectures. This is obviously just the tip of the iceberg, and YUTorah is the source, but users might find this an easy way to access his recent and some classic lectures: Rakeffet.Wordpress.com.
Also note that this website is presented in conjunction with the publication of R. Rakeffet’s new book, From Washington Ave. to Washington St., published by OU Press and Gefen Publishers. Learn more about the book here: link. From what I understand, it will probably not be available in the US for at least another month.
