The installation Aõ (1981), a work by Tunga (born in 1952, lives and works between Rio de Janeiro and Paris), consists in a 16-millimeter film projection that spreads out into the room. The unspooling of the film creates a large ring on the floor, resulting in both a cinematographical and spatial device. On the screen, a shot of a few seconds filmed around a bend inside the Dois Irmaõs tunnel in Rio is projected in a loop. This repetition creates the impression of a never-ending journey that is amplified by another repetition, a short clip from the song Night and Day by Frank Sinatra. The illusion of an infinite progression seems to bring time and space to a standstill. This loop, producing an impression of cyclical time, is in opposition to a continuous and infinite conception of time. Repetition and looping are recurrent in Tunga’s work. The objects and materials used are subverted from their intended function and poetically deliver metaphysical interrogations about our contemporary world. All of the artist’s works answer one another, and they create powerful physical and psychological tensions.
