Book and CD set
Has drums and piano on one side, bass on the other on the CD. Course starts simple and gets you into walking bass in a variety of keys. Having good quality track to play with really sounds good and helps you keep good time.
I would have liked a little more on blues, bluegrass, country and rock, but if you can do the jazzy things in here you can certainly play most blues and rock.
I think most bassists could benefit from working through the book - the exercises get more challenging, and it is fun to play along with the CD.
I was lucky to find it used in excellent condition at a book sale at a library - so keep your eyes open for cool things like that!
