If there is such a book, how would you write it? What are the chapters that you are going to put down? Well, Dummies in this sense might just point to casual listeners or just rock fans (like myself) who just do not "get" jazz. I own 3 albums, Heavy Weather, This is Jazz (Weather Report, The Jaco Years), and the Debut Album. I just don't get Donna Lee. I soon realized that I am not musically sound enough to appreciate a lot of jazzy stuffs. The album that I can enjoy most is the Heavy Weather. But I have got a listen to what jaco have played in the Live in New York City Vol 2 Album, especially his covers of Wipe Out, Cissy Strut and Dear Prudence. I felt that Wipe Out is a good show of his speed. And Cissy Strut and Dear Prudence is a good show of his musical ability. And the two songs are easier to the ear of a rock fan compared to the tunes of Punk Jazz or River People. I am still pretty much amazed (especially after listening to the orignal version), that how much Jaco can play in the two covers, he basically hold down the root, and play some harmony and play some melody, while not getting in the way of the guitar solo. I mean, giving the bass roles, I would have expected a normal bass players to just create some 1-2 bar grooves, and just repeat and repeat it over again, but Jaco, no, he seems to be able to come up with something new every 1-2 bars. Well, as much as I still do not fully "get" jaco yet. I felt that every Bass Player should be introduced to him, and should understand him. Such a book would be a very nice thing to have!
