I must say it is strange album, almost a long collection of unfinished songs.
Almost no vocals, apart from one song, and a few words from Stephen Hawking in another song.
I have to say if it was not a Pink Floyd album, say an album by a new unknown group, it would not have got the interest, or applause, it has got from some people.
It has lots of almost recognisable bits from songs you know from their other albums. 'Voices in the crowd' was definitely in there . Bits of 'Us and them', bits of 'Wish you were here.'
I don't think anyone else could have produced anything remotely similar
