I got a copy of this. The detail is perfect. Sure, Chantry brilliantly pioneered the "tool catalog" look. But here Jeff has perfectly captured the look of this genre for the band with the right name for it.
I have a self promo poster by another well-known (not for gig posters, but well-known anyway) Seattle design studio which attempted this look. Side by side with Jeff's, theirs is pitiful.
