I only have the Biz Markie mix which for some reason also got a vinyl release in the US and isn't hard to find. It's great! Heavy on rare groove, loads of great tunes and Biz's rough and ready mixing style and rapping.
All the mixes are on Mixcloud if anyone is interested.
I was lucky to see Geri perform many times over the years. Phenomenal player. She wasn't much older than me, so I was just as shocked as everyone when she passed away. Cancer sucks.
