On his fourth release as a leader, pianist Danny Green does something highly unusual and impressive: he gives us an album that consists entirely of what is, in every discernible way, straight-ahead piano-trio jazz, with no wild harmonic or structural experimentation, but which nevertheless sounds entirely personal and original. It's really kind of frustrating: I keep listening and trying to figure out how he does it, and I keep failing. Now, I should point out that three of these tracks feature a string quartet in addition to his trio, and that could reasonably be characterized as an example of structural experimentation. Fine, whatever. Nevertheless, even on those tracks this music feels both entirely straight-ahead and entirely new and personal, and dang if every single tune isn't utterly gorgeous and engaging. The field of piano trio recordings is a densely crowded one, and standing out in it is tremendously difficult. Danny Green sounds like he's doing so almost without effort. How does he do it?
