Prefuse 73

Prefuse 73 can be seen with an Akai MPC 500 in this photo.

You could obviously tell that the equipment is Akai's Professional MPC 4000 because you could see the name on the equipment itself. And you know it's "Prefuse73" because he has his tag/logo on the MPC 4000. By the looks of the photo, I think he uses the MPC 4000 in his studio. - the image was uploaded in 2013.
