Hip-hop popularized sampling old songs to produce something new. While criticized by “real” musicians, I think it is a fantastic way of building novel concepts. You take samples from one song, maybe borrow more from another, you put them together, connect them and now you have a new concept which is the new song born out of these

But to combine and construct something new, first, you have to deconstruct and destroy something old. Like DJ Premier you know.
