John Scalzi had this on his blog recently. It's mostly classical string doing six covers of Bowie. Amanda Palmer, if I recall correctly, is Neil Gaiman's main squeeze. If you're familiar with the Hampton String Quartet and their album What If Mozart Wrote 'Born To Be Wild', Strung Out is very reminiscent.
The album is available on Bandcamp, and if you buy it before March 5, 54% of proceeds go in Bowie's name to the cancer research wing of Tufts Medical Center.
Listen to it. I think you might like it.
