materials. The group's first home-made musical instrument, the bass-pipe a vara (a sort of trombone), was created by Gerardo Masana, the founder of the group, by joining paperboard tubes found in the garbage and miscellaneous items. Forty years later, this instrument is still being used on stage. The first informal instruments were relatively simple, like the Gum-Horn, made with a hose, a funnel and a trumpet's mouthpiece, and some of them were born as a parody of musical instruments, which is the case of the latín (referred to in English as fiddlecan) and the violata, bowed instruments whose resonating chambers are made out of a large tin for processed ham and a paint can respectively, the marimba de cocos, a marimba made out of coconuts, and others. Inventor and instrument-maker Carlos Iraldi (1920–1995), as "Les Luthiers' luthier", was responsible for inventing several more sophisticated instruments, including the mandocleta, a wheel moves the strings of a mandolin, the bajo barríltono, a double bass whose body is a giant barrel, and others. After Iraldi's death in 1995 Hugo Domínguez took his place, and made instruments such as the desafinaducha, the nomeolbídet etc. Current members Carlos López Puccio: Bowed Strings (violin, viola, cello), synthesizers, piano, vocals, percussion (in some jazz songs), dactilophone, etc. Jorge Maronna: Vocals, fretted strings (guitar, bass, banjo, charango, lute, cuatro...), cello, synthesizers, etc. Roberto Antier: Vocals Tomás Mayer-Wolf: Piano, vocals Martin O'Connor: Vocals Horacio Turano: Vocals, drums, bass pipe, bass guitar, piano, saxophone Former members Gerardo Masana, founder (died in 1973): Guitar, bass-pipe, vocals, percussion, etc. Ernesto Acher (left the group in 1986): Piano, horn, trumpet, clarinet, drums, synthesizers, cello, vocals, etc. Daniel Rabinovich (died in 2015): Vocals, guitar, violin, bass-pipe, sousaphone, recorder, drums, etc. Carlos Núñez Cortés (left the group in 2017): Piano, vocals, recorder, accordion, piccolo, Bunsen flute, synthesizer, dactilophone, tambourine, washboard, etc. Marcos Mundstock: (died in 2020): Vocals, percussion, trumpet, synthesizer, etc. Shows Les Luthiers cuentan la ópera (1967) Todos somos mala gente (1968) Blancanieves y los siete pecados capitales (1969) Querida Condesa (1969) Les Luthiers Opus Pí (1971) Recital '72 (1972) Recital sinfónico '72 (1972) Recital '73 (1973) Recital '74 (1974) Recital '75 (1975) Viejos fracasos (1976) Mastropiero que nunca (1977) Les Luthiers hacen muchas gracias de nada (1979) Los clásicos de Les Luthiers (1980) Luthierías (1981) Por humor al arte (1983) Humor dulce hogar (1985) Recital sinfónico '86 (1986) Viegésimo aniversario (1987) El reír
