I watched a "Rockumentary" the other night that investigated the making of Dark Side. It had interviews with all the band members and AMAZINGLY they all seemed to be in agreement.

They analysed the musical structure of the songs, Rick Wright showing the chord sequences for "Great gig in the Sky" for example and the engineer, Alan Parsons, at the mixing desk explaining how it all hung together. Really fascinating stuff.

It made me realise what a MASTERPIECE this album really is.

Not withstanding the fact that it spent YEARS in the charts, it has to rate as one of the GREATEST albums of all time.
