Also known as the law of parsimony, Occam's razor (or Ockham's razor) is a scientific principle named after William of Ockham (c1287-1347). Put simply it means when you hear hoof beats think of horses before Zebras - unless your name is Johnny Clegg!
"Occam's Razor" is also the name of a very fine 9 minute 11 second guitar solo by Mr. Zappa. There are actually three guitarists on this track: Zappa, Warren Cuccurullo and Denny Walley.
"Occam's Razor" was recorded live in 1979 and appeared originally on the One Shot Deal album, released in 2008. Part of it was used in an earlier Zappa work, "Toad-O-Line," and on the even earlier track "Inca Roads."
