I learned a hell of a lot from listening to and eventually doing sound for and watching the Climax Blues Band. I think the album's called ''Big Blues'', and is all Willie Dixon reworks, there's only about 3 walking bass tracks but the bass player is great, nice Lakland 5502 too!, i literally learnt to 'walk' from listening to that, and stuff like Dave Brubeck and Blood Sweat and Tears, just listen carefully and try to make sense of why the player's playing what they are, and if you can't make sense of it, nick it anyway!
