Disclaimer. Nothing I mention will be original, as it's all been said before, but for what it's worth here's my take. I think over the years I've become more fond of 'Aladdin Sane' than 'Ziggy Stardust'. But initially I preferred Ziggy - not that I ever heard those two albums the first time round. I only got into the whole Bowie thing in '83 on the back of 'Let's Dance' when I was still in my early teens. I think once you get past the rush of hearing Ziggy the first few times, you're sort of done - though I still love it! With 'Aladdin Sane' you get a more varied/wider sonic soundscape, with a lot more piano, more sax and sometimes the use of backing vocalists - and generally a more multi-textured sound. So yeah! It's Glam rock and Hard rock with a more American sound, but it still keeps its British eccentricity, plus obviously you have the Stones influences as well (think 'Exile On Main St.') and the cover of 'Let's Spend The Night Together'. The album was given the "Ziggy goes to America" label, but equally you could say "Ziggy does the Stones" or "Ziggy does jazz" - courtesy of the ramped up sax on this record and the introduction of the classically trained pianist/legend Mike Garson. Other cliches, I love the famous iconic cover with Bowie rocking that orange-flamed mullet and the lightning bolt make-up across his face, as the persona of Aladdin Sane.
If you had to pick out the personnel/musicians that stood out the most on this album, it would be Bowie (obviously), Mick Ronson at his "riff-tastic!" best and Mike Garson - with his creative, amazing piano playing. The highlights, well everything really, you have so much to choose from, like: 'Aladdin Sane' (I still can't get over how manic that piano solo is), 'Drive-In Saturday', 'Panic In Detroit', 'Cracked Actor', 'Time' and 'Lady Grinning Soul'.
