On Friday and Saturday evening you can play along in the session, coming edition with 1 session leader per evening. Everyone can play at his or her own level. As an assistant (and anticipation :)) we already have a session book with lots of played tunes for you. During a session, of course, everything will pass, but there is a good chance that there are a few from the book. Do not hesitate and play along nicely, even if you only play the bass / chords.
There are also some videos available to learn the new tunes by ear.
