I ran across this break beat sample directory for “The Funky Drummer.” It’s an attempt to track all of the songs that sample James Brown’s “The Funky Drummer.” That’s quite a tall order, considering it’s been sampled (seemingly) countless times. The directory is just one of the sampled songs which can be found on The-Breaks.com. I suppose if I’m ever bored, I’ll submit some of the samples I know, which they’re missing.
Since the above-mentioned link keeps getting spammed, you may find [Sampling-Love] to be a better database of sampling sources. They’ve got quite an impressive list!!
