One of my favourite recent albums of the past couple of years is pianist Kris Davis' "Duopoly". This album features improvised duets between Davis and various improvisors. One such pairing finds pianist Kris Davis with drummer Billy Drummond on two tracks (the other piano/drums duets on the album features Marcus Gilmore). One selection features improvisations on the theme to "Eronel" and the other, a completely improvised duet statement.
Here's a Modern Drummer article about this unique collaboration:
And, fortunately for us, here is video footage of both tracks from the album:
I've always been a HUGE fan of Drummond's drumming and have known Kris since she was barely out of high school (!) During the summer of 1997 we played together in a piano trio at the Banff Centre for the Arts with bassist Solon McDade, participating in the summer Jazz workshop. Definitely a highlight for me and I hope to play with her again in the future. I look forward to hearing more creative projects and collaborations from Davis in the years to come.
