I hang around with a lot of other guitar geeks on the Rob Chapman forum, and over the last couple of years they have organised a series of jams. We pick a backing track, and anyone can record their own solo on top of it. Then some poor mug (so far, most often me) has edited them all together into a video.
The latest of these jams was based on a blues track, and here is the finished result!
I have a playlist on my YouTube channel with all of the RCF jams here. And if you want to come along and chat about all sorts of guitar stuff (not just Chapman Guitars, but that’s part of it), pop along to the Rob Chapman Forum.
