So, yet another re-issue of one of the most iconic British rock albums ever. Is it worth investing in again? Well, yes it is. After the total debacle that was the 30th Anniversary edition (marred by poor re-mastering and bad editing, although the bonus tracks were a slight saving grace) we have the 40th Anniversary. Newly re-mastered, it's a big improvement in sound, although still not perfect.(And has no bonus tracks - Boo!) It might sound like nit-picking but why have they persisted with the USA album mix of 'Starman'? To answer the question posed by another reviewer the original mix as it appeared on the UK vinyl and single had a much louder and drier piano build-up before the choruses, devoid of the phasing applied to the mix of the track on the American pressings of the album. All subsequent CD releases have used the US mix, depriving those of us who treasure our original UK vinyl a chance to own the track in digital format. Unfortunately, this re-issue is no different so the wait goes on. That aside, if you don't own this album already (and let's face it, if you're a fan of proper music you really should) then this is the one to go for. I won't go into detail about each track - suffice to say there's many high points here - but it contains some of Bowies' finest moments. Opening track 'Five Years' 'Moonage Daydream' 'Starman' 'Suffragette City' not to mention the closing song 'Rock N Roll Suicide'. A magnificent example of how to build a track from simple to grandiose in just three minutes. It's not Bowies' greatest album but it IS his most important and for that reason alone you cannot call yourself a David Bowie fan and NOT own it. 50th Anniversary anyone?
