For all his talent as a lyricist Roger is not a singer. There will never be another DSOTM, not sure why he would do this. Unfortunately, Roger made an error in judgement by leaving the band in the early 80's, he's still angry PF didn't collapse without him. So he's gonna try remaking every PF album with his own name to tie himself to the brand.
Pink Floyd is one of those bands where the sum of all the parts far exceeded the individual parts. Roger just can't come to terms with that, still trying to prove he was Mr PF, sorry, PF was 4, not 1.
This album is awful, IMO.
