Steven Isserlis, Peter Evans
"Martinu: Cello Sonatas" (CD)

I don't know these pieces very well, but the little bit of Martinu I've played tells me that these pieces were constructed using a lot of Martinu's favorite toys: rhythmic interplay and poly-melodic writing.

Isserlis lends his inimitable energy (which is lessened when you can't actually see him,) and the recording itself is really very nice.
