Reddit mentions of R. Crumb's Heroes of Blues, Jazz & Country

R. Crumb's Heroes of Blues, Jazz, and Country is a great little book. It is worth it for the CD alone if he's into the obscure old-timey blues. Also, wrap yourself in bacon.

I do, fine sir. There is a CD/book from Robert Crumb entitled Heroes of Blues, Jazz and Country. Fascinating original recordings from the 1920's onwards. The jazz songs are old yet you can't find more authentic and swampy, to my opinion.

I might add, Allen Toussaint's the Bright Mississippi. A masterpiece of the New Orleans jazz music.

It is the best I can do. Hope you enjoy it!

Alternatively to listening to music and practicing the pentatonic and pentablues (I've been doing that to), since blues is a lot about the spirit and mood, it helps to really know it's history and where it came from.

Try getting your hands on the PBS documentaries "The Blues" produced by Martin Scorsese and also, the comic by Robert Crumb.
