Which decade had the worst music?

[SlowwHand]

3rd century BC Hydraulos - Invented by Ktesibios (or Ctesibius), a Greek engineer, to solve the age-old question, "How can a person play more than one instrument at a time?" He created an air chamber in a tub of water that was filled by a hand pump. The pressure was regulated by the weight of water. Mechanical levers or switches would send the air to different pipes. Of course, the modern pipe organ was basically the same concept. By the 15th Century CE organs had grown to be the first additive synthesizers, using multiple pipes for each note, adding harmonic complexity as well as volume.

So much for Rick Wakeman, Keith Emerson, or Dark Side Of The Moon.
