On the post-war blues list there was a post about so videos of artists associated with the Music Makers Relief Foundation as well as a link to a very good review of the CD-DVD Various Artists - Drink House To Church House: Songs & Stories From The Roots Of America Vol. I & II. The review by Richard Marcus is well worth sharing.
I have the blog Jazz & Blues Music Reviews on My yahoo page. Tim sometimes writes brief reviews but is always interesting with links to articles from newspapers or magazine as well as podcasts. he himself puts together a very fascinating podcast of jazz and blues every so often.
One of the podcasts that I have been turned on to by Tim is illasounds, which has a number of wonderful, thematic podcasts of great jazz recordings. If you go to the page and down the list, you will even see a terrific one of classic acoustic pre-war blues. If you want to sample the music of Thelonious Monk, or early free jazz or some contemporary salsa, these podcasts are terrific.
