The main thing that I liked about it was the soundtrack, which was done by Ry Cooder, Bobby King, Terry Evans, and several blues musicians that included harmonica player Frank Frost. Frost actually made a cameo appearance in the movie, from what I remember, and he had one song on the soundtrack. I really liked the downhome feeling of Frost's song, "Cotton Needs Pickin'," which was a rowdy roadhouse rocker compared to most of the other songs on the movie's soundtrack.
Later on, I discovered a few other Delta blues artists, such as Big Jack Johnson, Sam Carr (who was also on the Crossroads soundtrack), and Booba Barnes. These guys led me to Earwig Record's album Rockin' The Juke Joint Down, by the Jelly Roll Kings, a trio that included Johnson on guitar, Carr on drums, and, yep, Frank Frost on harmonica and keyboards. I listened to that album over and over again. It was just mesmerizing to this young blues fan.
One of my favorite songs on the album is "Pocket Full of Money." I actually heard it first by a West Coast blues band called the Fremonts, sung by Mighty Joe Milsap. The Fremonts is a fine group who play outstanding Delta and Swamp blues covers and original tunes, and you should really check them out sometime if you're not familiar. However, I really like Frost's version of this tune with it's relatively laid-back musical and vocal approach. I hope you do, too.
