Bowie 24 bit remasters....


are these superior to the older Ryko versions with bonus tracks?

I would agree with Ben,
The Ryko's were brightly lit remasters, and are worth more used because of the bonus tracks. The newer remasters did away with bonus tracks and only offer very slight sound improvement.
The 30th anniversary editions of Ziggy & Aladdin Sane are newer and much better remasters, best CD versions of either album I have heard.........plus deluxe packaging and 2nd bonus disc.
Actually, I think there are 2 remasters of "Let's Dance." I think EMI remastered Bowie's 80's catalog in the mid-90's (with some bonus tracks) shortly after Rykodisc did his earlier stuff. Then Virgin released a new 24 bit remaster a few years ago.

I've only heard the original CD version of "Let's Dance" (and not recently) so I can't speak to the quality of any of these.
