Watch the Big Blue Groove - Rhythm online guitar lesson by Jeff Scheetz from Rock Solid
Anytime a bunch of musicians get together to jam, and may not all know the same songs, a great way to break the ice is with some type of bluesy jam.
This usually gets the juices flowing. This one is great for that because while it is a standard 12-bar progression, it is pretty energetic and groove oriented, with lots of room for jamming. Kick into this one the next time you find yourself in a room with a band and I guarantee that they will jump right in!
