This is from the backing track collection I did for the book. I'll probably be putting out the first 6 tracks with charts and lessons as a separate download in the lesson store and then do the rest in a few weeks but I thought it would be fun to maybe get the BT jam ball rolling again with this.
If you click on the Soundcloud logo in the upper right corner of the embedded audio above it will take you to the page for the BT and thee is a download link under the music player on their page
It is a 12 Bar Blues in A...Here is the PDF with the parts on it: http://markweinguitarlessons.com/p/Shuffle4jam.pdf
Have fun!
