The 20th Jornadas de Estudio de la Imagen is the kind of luxurious discussion event that happens regularly here in Madrid.

A sprawling exhibition now at Museo Reina Sofia (through October 3, 2011; then traveling), “Magnetized Space” looks at the work of the junior partner of the Brazilian Grupo Frente. Pape was a co-founder of that 1954 initiative with the better known Hélio Oiticica and Lygia Clark.
