Sampling/Sampling

Chromatic Musings points to an interview with Chuck D and Hank Shocklee:

Stay Free!: There's a noticeable difference in Public Enemy's sound between 1988 and 1991. Did this have to do with the lawsuits and enforcement of copyright laws at the turn of the decade?

Chuck D: Public Enemy's music was affected more than anybody's because we were taking thousands of sounds. If you separated the sounds, they wouldn't have been anything--they were unrecognizable. The sounds were all collaged together to make a sonic wall. Public Enemy was affected because it is too expensive to defend against a claim. So we had to change our whole style, the style of It Takes a Nation and Fear of a Black Planet, by 1991.

Shocklee: We were forced to start using different organic instruments, but you can't really get the right kind of compression that way. A guitar sampled off a record is going to hit differently than a guitar sampled in the studio. The guitar that's sampled off a record is going to have all the compression that they put on the recording, the equalization. It's going to hit the tape harder. It's going to slap at you. Something that's organic is almost going to have a powder effect. It hits more like a pillow than a piece of wood. So those things change your mood, the feeling you can get off of a record. If you notice that by the early 1990s, the sound has gotten a lot softer.

"It hits more like a pillow than a piece of wood." I'm still pondering this.
