The best way to prove competency in a field is to show a working sample of your work to the client. GGRP wanted to show off their sound engineering capabilities so they contacted ‘Grey Canada’ which is an ad agency located in Vancouver, Canada.
They then created a record player from a piece of corrugated cardboard that folded into an envelope. Once assembled, a record can be spun on the player with a pencil. The vibrations go trough the needle and are amplified in the cardboard material. (See image below) This was then sent out to creative directors across North America
