Last year we went through a found-again-lost-again cycle for free, downloadable versions of the album Spirituals by the 1970's Breath of Life Quartet. It's back to "found again," this time on Grooveshark. But if you find this post by googling and are interested, I advise you to grab the tracks quickly lest they disappear again. Great black quartet singing. If you want to read a few more of my thoughts about the group, here's the post from last year.
And here they are, thanks to Grooveshark: The Breath of Life Quartet.
