On Bordoneo y 900, Juan José Mosalini wanted to base his orchestra and his music on the original Argentinean ensembles from the 1920s -- piano, double bass, two bandoneons, and two violins -- that spurred the tango. Later on, in the '40s and '50s, the orchestras grew bigger. In writing tangos, the work of the arranger may be more important than that of the composer; it is the arranger who gives life to the music. On this CD, Mosalini shows his arranging skills (he did not include any of his compositions), enlarging, for example, the strings with a few more violins, a viola, and a cello. This instrumentation gives Bordoneo y 900 a quite mesmerizing classical characteristic, but it is the arrangements that are the most original. A must for tango lovers. ~ Bruno Deschênes
