El Grosso Concerto, opus 58, fue un espectáculo del conjunto de instrumentos informales Les Luthiers en compañía de la Camerata Bariloche. El título, El Grosso Concerto, es en realidad una variación del título de una obra incluida en el espectáculo: el Concerto grosso alla rústica (un verdadero concerto grosso barroco, al estilo de Vivaldi). Esta obra fue compuesta por el compositor ficticio Johann Sebastian Mastropiero, inspirado en un poema del "famoso" poeta ficticio Torcuato Gémini. El título de la obra no tiene nada que ver con la forma musical de que se trata (el concerto grosso barroco), sino a la dedicatoria que le hizo Gemini a una regordeta y tosca doncella del altiplano argentino, a la que iba dedicado el poema. Dicha dedicatoria decía así: "Con certo sentimento d´amore, alla signorina grossa e rústica".
