Today's talks complement the "Critical Constellations of the Audio-Machine in Mexico" exhibition and are also great primers for two days of concerts with many of the same Mexican sound artists, coming up at HAU2 on Wednesday 1 and Thursday 2 February. Angélica Castelló, Guillermo Galindo, Ariel Guzik, Roberto Morales Manzanares & more give different visions of music and sound against the backdrop of Mexico's nation-state project from the 20th century until the present.
