This is THE Pink Floyd album. Deep but catchy. Listen to the whole album. From the boat rowing (Signs of Life) thru the urbanized jungle concreted mega-cities wailing of David Gilmour's guitar, followed by Nick Mason's foot pedal on drums (Sorrow) with your tongue-in-cheek concentration. Even A New Machine (pt 1 & 2) has much more depth than it sounds. Love it forever as it if was your own temple's music.
Progressive Classic Rock at its best!!
