I came across a pretty cool site that features Interviews and live concert recordings free to listen. You have to register, so I advise using a free hotmail address, to avoid the possibilities of receiving spam mail.

I checked out the Sly & The Family Stones Filmore East New York, NY Oct.5th '68 show. The audio is cool.
