Pim,
I am jealous of your Mal Waldron collection! That's fantastic. Isn't it so fun to completely immerse yourself in an artist's work!?!?!
Also, I really hope you do the blog thing and describe your impressions of each recording! I have about 50 Waldron recordings. Nothing to sneeze at -- but I'm sure I'm missing some great stuff. So I'd love to hear/read your impressions.
One question: Since I have none of them, which of Waldron's Tutu recording do you like best?
