"The composer, pianist and bandleader Guillermo Klein lived in New York from 1993 to 2000 before moving toArgentina, where he's from, and Barcelona, where he currently lives. But he was a source of inspiration, and he is still talked about. His jazz, if you want to call it that, is built from the ground up, starting with ideas about instrumentation, then rhythm, then harmony, then gesture. In one of his large ensemble sets, there could be brass choirs, Cuban rhythm, fuguelike passages, talking, whistling, mechanical repetitions over a groove, and bits of aerated rock.

Over the last 15 years or so, the pianist and composer Guillermo Klein has made a study of the tensile and elastic properties of rhythm. Along the way, he has built some fascinating bridges between jazz, pop, classical music and the chacareras and tangos of his native Argentina. His best music also carries smart harmonic ideas and surprising bolts of lyricism, but virtually all of it deals purposefully with the subject of groove.
