Listening to any of Pink Floyd's work is an adventure of the mind. Seeing (and hearing) it happen is amazing.
Pink Floyd reunited for this 1988 CD (minus Roger Waters, and of course minus Sid Barrett). Bob Ezrin was again a guiding light in the producer's (and musician's) chair. This album was the one that truly brought Pink Floyd into the 'modern era' (this modern era... we don't yet know what the next one will be). The tracks are chock-full of late-1980s, state-of-the-art recording technology and technique (...and from my perspective, late-1980s synthesis and sampling technology and technique).
in a slightly-related aside:
I always think of this album in the same breath, as when I really discovered the possibilities of Paul Crowther's great 'Hot Cake' guitar pedal. Paul 'Emlyn' Crowther was a drummer in Split Enz, and he designed it to help Noel Crombie get a better guitar sound (or so the story goes). I've used that pedal many, many times in the last 20 years.
