As we investigated the myths surrounding the bluesman Robert Johnson for our short Crossroads, we found ourselves swimming in amazing music -- not just blues -- and we wanted to share it.

So here are all the songs featured in the Crossroads podcast, in all their full-length glory. When you line them up, you've got something of a history of the roots of rock n' roll. Oh, and we should point out, this isn't quite everything. A few rare, old tunes weren't available on Spotify, but you can buy 'em at iTunes or Amazon, if you like (links at the bottom of the page).

Enjoy!
