Argentine guitarist, composer and arranger Rodolfo Alchourrón leads his own band in these two LPs from 1972 and 1974. The result is a jazz-tinted sound which incorporates elements of rock, soul, lounge, film soundtracks and even tango. Rodolfo Alchourrón’s figure holds a special place in Argentine music, both for his intense production as well as for his ability to set up bridges between different musical genres. Born in 1934 in Buenos Aires, he received a solid classical music formation. Later on he became interested in so-called popular music, attracted by jazz, but also by tango and rock. In the jazz scene he played with musicians as renowned as Leandro “Gato” Barbieri and Enrique “Mono” Villegas. In the tango arena, he collaborated with Eduardo Rovira, Astor Piazzolla and Rodolfo Mederos. In rock, he’s well known for his orchestral arrangements for Almendra, Miguel Abuelo and Litto Nebia. Nor was he a stranger to Argentine folklore: he played the charango and shared the stage with musicians such as the percussionist Domingo Cura or the fusion accordionist Dino Saluzzi. Since the 60s, Alchourrón founded and directed a great diversity of groups: from trios up to a big band of 16 players. It is in this context where we can frame his experiences with the Sanata y Clarificación project, dating from the period between 1970 and 1974. The band, made up of top-level musicians, proposed a musical interchange between jazz and rock which was rather unusual in the framework of the music produced in Argentina at that time. They released their first LP, “Sanata y Clarificación”, in 1972 on the independent label Promúsica. With great space for instrumental improvisation but without nevertheless related to some soundtracks from films made in that period, especially in Italy. In 1974 the band released their second LP with some changes in the line-up. Simply titled “Sanata y Clarificación Volumen 2”, the record continues the first volume’s proposal, intensifying the arrangements, the melodic lines, the instrumental solos and trying out approaches not only to jazz and rock but also to waltz and tango. The instability of the local context and the difficulties to promote a project which lacked a commercial orientation provoked the break-up of the band that same year. In 1978 Alchourrón emigrated to the United States and settled in New York, carrying on with his work as a composer and arranger. Around 1989 he returned to Buenos Aires, maintaining his musical activities until his premature death in 1999. His legacy comprises nine records, plus countless discographical appearances and several published books on composition, arrangement and improvisation.
