"Alfredo Costa Monteiro was born in 1964 in Porto (Portugal)

Lives and works in Barcelona, Spain.

He studied sculpture/installation at the fine art school in Paris with Christian Boltanski.In 1992, he moved to Barcelona. Since then, his work stands somewhere between visual arts, visual poetry and sound. His installations and sound pieces, all of a low-fi character, have in common an interest for unstable processes, raw materials and gestures, where the manipulation of objects as instruments or instruments as objects has a strong phenomenological aspect.

From 1998 to 2006, he was member of espai 22a, an independent collective for contemporary art. From 2001 to 2006, he was also member of IBA col.lectiu d'improvisació

In sound poetry, he performs in solo polyglot and noise pieces ( portuguese, french and spanish), where sound establishes a different semantics.

Ongoing sound projects: Cremaster (with Ferran Fages), i treni inerti (with Ruth Barberán), Atolón (with Ferran Fages and Ruth Barberán), Astero (with Juan Matos Capote), 300 basses (with Jonas Kocher and Luca Venitucci) and duos with Pascal Battus, Tim Olive and Michel Doneda.

He has given workshops at Hangar (Barcelona, Spain), ESDI (Barcelona, Spain), Janácek Academy of Music and Performing Arts (Brno, Czech Republic), Arteleku (San Sebastián, Spain), Facultad de Bellas Artes, (Pontevedra, Spain), ESAD (Caldas da Rainha, Portugal), Crossroads during John Cage's Year, (Lublin, Poland) among others.
