Below are great examples of how you can take a three-piece band and cover songs as layered and busy as Electric Light Orchestra's Mister Blue Sky and many others.
You are about to hear five or six short renditions of these classic songs. Assuming you are a trio with a drummer, keyboard and electric guitarist, the first three renditions will be played live by your band while the subsequent renditions come from your Colson Studios backing track.
To make this authentic you will need a live lead vocalist, but you might want your other two band members to sing along with the background vocals. Follow the Audio.com link below to listen:
