I remember that there were only two artists at Sevilla Biennale 2008 whom I found interesting; I can't recall one without looking back to my journal but the other was the Mexican-Canadian electronic artist Rafael Lozano-Hemmer . He also caught my radar at Basel Art Fair in 2009. So I am pleased to see that he has a solo show called Recorders at Manchester Art Gallery. It features seven recent pieces of which I think I recognise a couple from the previous installations. Lozano-Hemmer’s artworks depend on the participation of visitors to exist and develop, as the artist describes: “In Recorders, artworks hear, see and feel the public, they exhibit awareness and record and replay memories entirely obtained during the show. The pieces either depend on participation to exist or predatorily gather information on the public through surveillance and biometric technologies.” Highlights of the exhibition include Pulse Room, on show in the UK for the very first time. Premiered in Puebla, Mex
