This is a great series, one of the best I've seen. These arrangements sound good, are easy to learn (for advanced players), and are in the "common" fake book keys. There is room to add your own ideas and you can play these with other musicians who are using fake books. I have played so many of the "Look at what I can do" variety of arrangements and find these better for gigs. If these arangements are too dry and bare bones, then you must be a seasoned jazz player who should be doing your own arrangements.
