Welcome aboard to Captain Beyond’s Quadraphonic Wormhole, a portal in time to a place where sailing the cosmic seas of four channel sonic endeavors can be experienced once again. This website is devoted to matters concerning legacy quadraphonic music from the 1970’s. This would include documents, equipment, legacy releases, formats, history and any other notions of a quadraphonic nature. Respectfully with your help and hopefully your contributions this site could become a repository of all things quad. So let’s hoist the mainsail. Forward into the past!
