I also went to the 30's material to see how Mojo would handle them: Mississippi John Hurt's early recordings and Bing Crosby's complete set, particularly the early recordings. Blind Blake, and a few others. I thought of this when one reviewer referenced a 57 recording of Elvis and how Mojo brought it to life. The 30's recordings are more enjoyable now. Mojo expands my hobby greatly, both in brining back old material while being inspired to listen to new.
