I have three buddies that I play guitar with all of the time. Each of us play a different style of guitar. One plays the acoustic guitar that has a mainstream sound. The other plays classical guitar and has picking skills that are out of this world and I play electric guitar. We were trying to think of a way to make some money doing the thing we love the most, playing guitar. We taped a jam session one night and showed it to a friend of ours who is in video design. He made a guitar instructional video out of it and we were able to sell it.
