Station To Station, as many reviewers have pointed out, is a fairly short album in terms of the number of songs that are recorded on it. However - the album still clocks in at a decent length. And song for song, it's a very strong line up. Bowie's vocals are great throughout - and each tune engages the listener accordingly (even the cover of Wild is the Wind - not many male artists could pull that off with so much repressed emotion).
STS is a great listen - and I for one would rather have 6 strong songs than 11 or 12 that have been padded out (heresy it may sound but I think Aladdin Sane and Diamond Dogs are guilty of this - only by one track but it illustrates how less can sometimes be more).
But it's the mystique behind the album, the relentless progression of Bowie musically, if not socially - that grips you as you listen. Tales of him not being able to remember anything of it's recording are littered about the web - but who cares whether or not he does? If I were able to come up with an album of this quality - delivering vocals of this standard - I wouldn't care what edge of reality my life was on at that particular moment.
Diamond Dogs (despite my comment above), Young Americans and Station to Station are all singular entities, and somewhat unique - but all three contain some of Bowies most ambitious and, IMHO, best work. 5 stars, easy.
Ps The story of Iggy Pop's acid dream influencing TVC-15 is always going to bring a smile, regardless of the amount of truth in it.
