Jojo Mayer is one of my favourite drummers and he's undoubtably one of the greatest drummers alive today.
This solo has a bit of everything. It's musical, technical, dynamic, surprising and built on a cohesive set of ideas. A great example of what makes an engaging drum solo.
What really stands out to me is his use of volume. He utilises a very broad range of dynamics. It's so easy to just play loud all the time, but that's pretty boring to listen to. And once you've reached full volume, that's it, you can't go any louder. Contrasting loud with quiet keeps things interesting, and holding off playing your loudest will mean you always have somewhere left to go.
One of the easiest ways to improve your drumming and soloing is to pay more attention to your dynamics. Jojo keeps you waiting, he teases, he explores the extremes. And that's what keeps you listening.
