A great William Gibson essay on the culture of sampling; the post-modern validity of ripping, mixing and burning, and the whole realm of creative possibilities birthed by the Tech Bloom:
Our culture no longer bothers to use words like appropriation or borrowing to describe those very activities. Today's audience isn't listening at all - it's participating. Indeed, audience is as antique a term as record, the one archaically passive, the other archaically physical. The record, not the remix, is the anomaly today. The remix is the very nature of the digital.
Today, an endless, recombinant, and fundamentally social process generates countless hours of creative product (another antique term?). To say that this poses a threat to the record industry is simply comic. The record industry, though it may not know it yet, has gone the way of the record. Instead, the recombinant (the bootleg, the remix, the mash-up) has become the characteristic pivot at the turn of our two centuries.
