My best friend in high school in the '80s had something on his home stereo I've never seen before or since: an 8-track tape recorder. We would make 8-track mix tapes and take them to parties ... which we promptly got kicked out of because they were tapes of stuff like Yes, King Crimson, Laurie Anderson, Tangerine Dream and Vangelis, and didn't nobody want to listen to that kind of shit back then.
