Paul DeMarinis has been working as a multimedia electronic artist since 1971
.....

"Ich auch Berlin(er)" (1990)

A tribute to the Berlin(er) brothers, Emil, Irving, and John Fitzgerald. A
gelatin dichromate hologram of a 78 rpm record of the "Beer Barrel Polka" is
rotated on a transparent turntable and played by a green laser. Once I
realized that only light reflections were needed to make the recorded
grooves audible, it became apparent that a hologram (the memory of light
reflecting from a surface) would suffice to play music. Here, sans needle,
sans groove, the band plays on.

I remember reading about this in the early 90s.

wood or assign them tasks and work, but rather teach them to long for
the endless immensity of the sea."

Not yet practical for ordinary home use, but strange and amazing
nonetheless.

    An anonymous reader writes "[0]This site describes a method of
    extracting audio off of scanned images of vinyl records. Kazaa vinyl
    swapping is on it's way!" While this method creates exceptionally noisy
    samples, you can definitely hear the underlying music.
