Alright, this guys loves his vinyl, but youre not going to buy any used LPs from him. Records, to him, are meant to be spun and scratched, and he will take them out to parties along with his aged Technics (or two) to show his mates his skills.

The scratch disks are different story, but the ones played at party should be very clean and have no surface noise.
