Editors’ Notes

The Argentinean pianist/composer Guillermo Klein has led large jazz bands dating back to the 1990s. On 2008’s Filtros, he heads up an 11-man version of his group, Los Guachos, and the result is stunning. He incorporates a lot of elements into his music: jazz, modern composition, Argentinean folk, and the superb instrumental abilities of his band members, including the saxophonists Miguel Zeñon, Bill McHenry, and Chris Cheek. Filtros opens strongly with “Va Roman,” an expansive song that finds Klein on lead vocals. The track has its own distinct sound, but it also brings to mind the work of the sui generis British musician, Robert Wyatt. On “Miula” and “Luz de Liz (Filtros),” Klein uses an intriguing compositional device that gives the impression that the music is slowing down or speeding up as the beat stays the same. Klein’s choices of “covers” are more than a little interesting. He incorporates parts of Gyorgy Ligeti’s Hungarian Rock and an Argentinean folk song into “Vaca,” and the album closes with a version of Louange Á L’Éternité De Jesus, by the formidable French composer Oliver Messiaen.

Catch up with Klein

Guillermo Klein is one of the most innovative and exciting composer/arrangers in improvised music. I've followed his career since the second Los Gauchos recording, and have yet to be disappointed. He has the ability to structure pieces so that every instrument is clear and engaging. The way he plays with rhythm, with canon-like countermelodies, and with lyrical ideas of memorable beauty all make his work highly recommended.


This is the most original and exciting jazz-related large ensemble music I've heard in quite some time. I say "jazz-related" because calling this just "jazz" would be limiting. Klein has come up with a sound world all his own. He has a great band full of strong and individual improvisers and players, but utilizes their soloing talents sparingly and only when it makes sense in the context of a particular piece. Several soloists, most notably Miguel Zenon on alto saxophone, get their chance to shine in selected spots. All of the musicians' own voices can be heard featured in Klein's melodies and voicings...he really writes for this particular group of individuals. In this release, Klein's gift for strong, memorable melodies has really come into focus much more so than in past releases of his.... check out "Yeso" in particular. He also has a way with catchy Latin and funk derived grooves in complex meters... check out "Miula" and "Snake" (also catch a memorable Bill McHenry solo on the latter). He has come up with a unique method to make it occasionally sound like the time is "stretching". Check this out on the transition sections of "Miula" and throughout most of "Luz de Luz" (Although "Luz" could use a little editing in spots....this is really the only slight mis-fire (imho) on a great cd. There is a beautiful piano/guitar duet towards the end of this track that sounds to me like bossa meets Steve Reich, however) Klein and Los Guachos have melded the sonorities of Duke Ellington, Wayne Shorter, contemporary classical music, Argentinian music and much more into an unforgettable and beautiful sound package all their own. Get this music now!

Filtros Los Guachos Guillermo Klein

At last...original jazz that isn't from Denmark. Guillermo sounds like Stan Getz and Gerry Mulligan rolled up together. Billy McHenry rocks.

Guillermo Klein moved from his native Argentina to Boston in 1990 to study at Berklee College of Music. In 1993 he moved to New York where he formed an inventive 17-piece big band. The band played Sunday nights at the underground club Smalls throughout 1995. Several years later, a newer, larger club called the Jazz Standard gave the Guillermo Klein Big Band a regular Monday night gig for several months. Klein also performed and recorded with a ten-piece ensemble called los Guachos, which featured...
