I think we have to be realistic about these albums - none of them really. stand comparison with any of the 70s work, but that’s not surprising as Bowie’s work in the 70s represents a sustained period of creativity that no-one has ever matched in the history of popular music. No-one could expect to be still sustaining that level 20 years later. That doesn’t mean there is no value in them though.
There are records I could never bring myself to listen to in full (Tonight, Never Let Me Down, the two Tin Machine records). Even on those there are some great songs - Loving The Alien for instance. There are a fair few albums where you can sense him desperately seeking a new ‘idea’ that will take him somewhere interesting. Sometimes this is pretty successful (Outside, Buddha of Suburbia) sometimes less so (Earthling). Those projects are all patchy but fascinating.
In a sense Let’s Dance is similar in that the ‘idea’ was to make a massive pop album. It’s successful in that its singles are brilliant and it was massively commercially successful. I’ve always wondered why the rest of it is so poor. It’s probably the mark of Bowie in this period that, unlike in the 70s, he often doesn’t seem to have quite enough material to fill a whole album. Hence perhaps the number of lacklustre covers on some of these albums.
The interesting thing about Heathen is that I think he relaxed a bit and stopped trying to reinvent the wheel or strive for either massive commercial success or cutting edge ‘relevance’. I think this was probably influenced by working on the Toy project as I’ve said above. The result is a really consistent set of songs for the first time since Scary Monsters. Even the cover version (of Cactus) is really great.
What is really amazing is that, against the odds, when it came to making Blackstar he did match and arguably even surpass his 70s work.
