Sonamos, pese a todo by Les Luthiers

Sonamos Pese A Todo, the debut album of Les Luthiers, released in September, 1971. It was recorded in late 1970 at ION Studios in Buenos Aires, and it featured Les Luthiers as a quintet, with some guest musicians and an orchestra for some numbers. The album was done before they collectively credited their works to everybody in the group, so individual authorship is included. Ernesto Acher wasn't a member of Les Luthiers when they recorded the project, but he was instrumental in getting the album released.
