| Similar in what way? Instrumentation-wise, it's all pretty much piano, alto sax, upright bass, and kit; and it's the same four guys playing them (Brubeck, Desmond, Wright, and Morello respectively) with the same musical sensibilities.
I think that if you're looking for variation you might need to dig a little deeper and go to the songs themselves. Even in something like Blue Rondo you've got a frenetic 9/8 juxtaposed against a lazy swing section. There's a square dance in 7/4 (OK, as Brubeck would call it, an "un-square dance").
If there is an artist worthy of deeper study, Brubeck is definitely it, so don't wait-- and go see him live while you still can, he's still got his chops even in his mid-80s.
And listen to him talk sometime about the stuff he had to go through in the 50s and 60s because he employed Gene Wright, a colored bassist. |
