@geof3, yeah.
A couple of years ago now I learned about a drummer that has the most amazing rapport with his piano player, their work together is really extraordinary in that aspect. His name is Ofri Nehemya and he plays with the Contemporary Jazz pianist Shai Maestro. Try the album The Dream Thief if you’re interested.
Another drummer that when listening back has really just amazed me lately is Danny Carey. You undoubtedly know his work with Tool but have you ever heard him play with Volto!? I think they felt they could just let go and show their stuff and really experiment on that one amazing jazz-rock/experimental record they made. It’s jaw dropping stuff for me.
Neil Pert was my favorite drummer but with him gone I think I’d probably pick Gavin Harrison as my favorite these days. I especially like his work with The Pineapple Thief but he makes everything he’s recorded on better.
There are many others that could be discussed. Who are some of your favorites?
