Discovered Ronnie Earl last year and bought most of his "Broadcasters" albums. Currently, I still must frequently hear some tracks from "Now, My Soul", particularly "Double Trouble", with Kim Wilson on vocal and harp - his harp solo still knocks me out.
"Grateful Heart" is a tad jazzier than blues and has 3-4 cuts I revisit frequently. In fact, I use "Skyman" as a test piece when I swap cables, or roll tubes.
Ronnie's slow blues tunes are his signature to me, and although his guitar work is exceptionally flavorful, I dig his work as much for his keyboard players as his guitar work there. Bruce Katz or Dave Limina on piano OR B3. The bomb, through and through.
