I love mash-ups. Having said that, I realise that 'mashing-up' is an art that is not easily mastered. So many of the mash-ups you see are simply vocals from one track, mixed with iconic beats, usually involving but not limited to the Black Eyed Peas, Jay-Z, or the ever-green Vanilla Ice.
G.reg, a colourful character from Australia, is on his way to mastering the art of the mash-up. If you don't believe in mash-ups, or don't believe me, check it out for yourself:
