Ben Paisner’s books on swing style are legendary. There are many many books from his catalogue, and qPress is going to publish as many of them as possible.
As opposed to his book 30 Studies in Swing, this book is aimed more at the intermediate level player. Someone who has the facility to play more in-depth, technical, and involved swing tunes. He still gives the same great instructions at the top of each tune to let you know what to watch out for, and the tunes each have full chord changes to help you make sense of what is happening harmonically (and to play along with a pianist).
You should grab your horn right now and play the first two tunes for free in the samples. Then you can grab an immediate PDF download above.
