Ernesto Acher

Ernesto Acher (October 9, 1939 – December 12, 2025) was an Argentine comedian, actor, composer, arranger, multi-instrumentalist and orchestral conductor. Between 1971 and 1986, he was a member of the celebrated Argentine group Les Luthiers, with which he acted as composer, comedian, singer, and performer on more than twenty instruments, some of which he created himself. Before separating from the group, he was involved in individual projects as composer – including a soundtrack, a quartet for clarinet and strings, a string sextet and a symphonic poem for viola and orchestra. In 1988, he founded the La Banda Elástica (The Elastic Band), gathering some of the most outstanding Argentine jazz musicians. The band dissolved in 1993. Since then, he has developed several musical and comedy projects and performed as an orchestral conductor.
