I have purchased many tracks from jazzbacks for both performance and practice. The tracks come with melody line notes and chord names but the guide tracks also offer a great option for learning the songs by ear.
Larry has been very helpful and patient with my beginner's questions over the years and I am happy to say that thanks to these backing tracks and Larry's help my playing has improved.

This track sounds very good, comes with a nice legible chart and instructions for playing it in case you don't know. Also the lyrics. I usually make my own but this one was one I needed quickly and it was free so what had I to lose. I'll be back if I ever need another back and don't have time to make it myself. Thanks.
