On guard, I'll let you try my Wu-Tang style!
You've heard em 1000 times, but probably never knew where they came from. Other than perhaps the more well known "Shaolin vs. Wu-Tang" that provided most of the samples for their debut album "Enter the Wu-Tang (36 Chambers)", most of the other samples are a mystery. Well no more.
Vega over at The Crypt takes care of that for you, with a complete list of the samples from each album, including the various Wu solo projects, and their source films.
