Here's a great documentary from the 80's on 4AD Records in-house design firm, 23 Envelope, run by designer Vaughan Oliver and photographer Nigel Grierson. As I mentioned a couple of years ago, their design work has defined the 4AD brand for the last 30 years, and continues to do so. The label would not be what it is without their serious contribution. Any regular reader has definitely seen their work.
This film features Vaughan and Nigel interviewed in the 4AD offices, along with interviews from 4AD head honcho Ivo Watts-Russel, Robin Guthrie of the Cocteau Twins, and more. It includes plenty of video footage from 1980's era 4AD bands as well.
