The Division Bell was the last studio album to be recorded by the band: David Gilmour, Nick Mason and Richard Wright. The album debuted at No 1 in the UK, the USA, Australia and New Zealand, staying at the top of the US charts for 4 weeks; it also went to No 1 in six other countries and, to date, has reached total album sales of over 12 million. The album was recorded by the band at Astoria and Britannia Row Studios with the majority of the lyrics being written by Polly Samson and David Gilmour. The Division Bell sleeve artwork was the first Pink Floyd image to be featured on a Royal Mail stamp, in an issue of ‘Classic Album Covers’. The iconic album artwork of the two huge metal heads in profile talking to each other (and in turn, creating a third forward-facing head) was provided by long-time Floyd collaborator Storm Thorgerson. The album was remastered for the release in 2014 by James Guthrie, Joel Plante and Doug Sax at The Mastering Lab from the original analogue tapes. Bob Ezrin and David Gilmour produced the original album, with orchestral arrangements by the late Michael Kamen.
