I recently purchased several different Jazzbacks backing tracks. They are excellent for practicing and I use them for solo performance in this challenging time. What I love is that changes in the tunes are accurate and most of all their is a real rhythm section feel, as opposed to a mechanical feel.
I initially had some problems with the downloads, (based on my ignorance), Larry offered immediate help and support. I couldn't be more pleased.

I love playing along to jazzbacks tracks.
Black Orpheus is another example of a thoughtful and inspiring arrangement.My audience and I thank you.
