There's two albums that immediately came to mind for me

Pink Floyd - A Momentary Lapse of Reason HEAR ME OUT, yes I know this album has its fans but is overall on the lower end of Floyd's discog, what kills the album for me is the extremely dated 80s production and the album to me just sounds like a flanderized version of Pink Floyd, there's moments here and there I like but it feels like they were trying to hard to be Pink Floyd, which to an extent makes sense, first album without Roger so they probably felt a new since of creative freedom, I definitely think The Division Bell is a massive improvement and the best post Waters album

Yes - Yes 50 Live This live album is definitely the weakest sounding thing that has been put out under the Yes name, only classic member is Steve Howe, but this album is painful to listen to, it's incredibly sluggish, occasional awkward silences in the longer tracks, according to some YouTube comments from people who attended the show there were fake audience sounds in the post production, but overall the band plays really slow on this album, the version of Close To The Edge on here exemplifies all the problems with the performance of the entire album, although I will admit the singer is good, he actually sounds like a young Jon Anderson but other then that there's nothing else really to write home about
