Query: beware of this bootleg

Despite the back cover notes stating that this recording is made live at "Viejo Almacen" it is not true. Atributing this recording as "live" has only one reason: to cover the terrible sound quality of this pirate release of the second session of "Octeto Buenos Aires". This recording is available on other CDs and have been rereleased many times (for evample by ANS records or by Blue Moon Records under the title "Marron y Azul"). Moreover, the opening track is missing here too.
