Maybe it's the bad audio quality, but I swear I'm hearing tons of leslie in there, sounds like B3, but could be one of the other boards through a rotary. The backline isn't completely visible. Could that be the Solina through the Leslie?
BTW: Bowie looks like he's got some serious chops. I've never heard him talk about his keyboard playing, but there's some movements at around 1:30 that show he really knows his way around the keys!
Equipment: Laptop running lots of nerdy software, some keyboards, noise makers…yada yada yada…maybe a cat?
