 The opera depicted the incredible decadence into which Argentina fell which led to economic collapse and a series of economic problems have been referred to as the “Tango Crisis.” "The Festival of the Monsters" was a short story written by Jorge Luis Borges and Adolfo Bioy Casares and it is with this in mind that Fogwill referred to "the monsters" in his book of poems "Lo Dado" ("The Given").In Edelstein's opera he creates two protagonists, Monstruo I (Juan Peltzer - Baritone), and Monstruo II (Lucas Werenkraut -Tenor).This was the second collaboration between Fogwill and Oscar Edelstein, the first being in 1997 where in Edelstein's work ""Klange, Klange Urutaú"" Fogwill translated and recorded a poem of Fernando Pessoa.
