Siren is an amazing trio recording by Uri Caine. This particular group - Uri Caine (piano), John Hebert (bass), and Ken Perowsky (drums) behaves like a single, living organism. They follow each other's subtle and not-so-subtle changes in rhythm or tempo, or harmonic change. It is uncanny how tight they are in a constantly morphing musical flux.
Another interesting observation: In this particular recording, I felt that Uri Caine is, at least spiritually, channeling the spirit of Herbie Nichols. By no means are they imitating him or stealing licks from him. It's much more subtle and profound than that. It is more a matter of utilizing a certain way of phrasing, and of utilizing certain harmonic changes/sequences, that (to me) strongly evokes the "feeling" of Herbie Nichols music. This trio appears to fulfill the prediction, made long ago by Herbie, regarding the future musical sophistication of jazz pianists, who, Herbie noted, will necessarily have a strong classical background which they will bring forward into the jazz context. They won't be overtly "classical" in expression; no, it is more a matter of having that level of technique and harmonic knowledge and bringing it into the jazz format.
I believe that Uri Caine is an exemplar of this philosophy, and he represents the ultimate fullness of bringing Herbie Nichols prediction into the piano trio format. Another similarity between Uri Caine's music and Herbie Nichols music: this ensemble is fully integrated in the sense that the music is NOT a case of piano genteely supported by bass and drums. No, this is a case of the drums moving up into the surface of the music, and of a fully realized "conversation" between equals.
To me, this recording is the best of Caine's work in the format of the traditional piano trio. It is truly 21st century jazz.
