Which album would you play first on the famous Bowers & Wilkins speakers at Abbey Road Studios?

[Revolutions]

Looks like they have studio ATCs in the landscape position, and the B&Ws with a matching centre, perhaps for video/film scores?

The left/right B&Ws were firing for the LOTR playback when I had the demo, so you may be right.

Same in studio 3 where they played Imagine mixed in 5.1. But thinking about it the speakers in studio 3 didn’t look like classic B&W. They had silver cones, much smaller.
