Sampling in music has been going on for decades and even before the digital age, mashups existed though they were called edits or Mega-Mixes. One of the most famous series was the Bits & Pieces mixes where the master tapes were created by literally cutting and splicing tape recorded pieces of music samples together until a new mix was created. It was tedious work and took forever.
Enter the digital age. In this iPod world, all you need is smartphone to get basic tools to create a decent mix of a popular song. Invest in better and proper equipment you can create something even more special. If the guys tweaking the knobs happen to be legendary DJ Armand Van Helden and Kanye West's DJ A-Trak, then you've got something kinda special.
Armand and A-Track hooked up and created Ducksauce and have put up some pretty choice club cuts in recent years. One of my favorites is Barbera Streisand that features Boney M's classic "Gotta Go Home".
Check it out and see if you can listen to it only once.
