Joining Grupo Ruptura in 1955, Lauand developed her practice within the bounds of their geometric language, working with precise sequences and mechanical order. Her early concrete paintings reflect the group’s rational and cerebral approach, though this is offset by her embrace of material textures and brushstrokes that allow the calculated compositions to retain a human touch.

Amongst the key figures of Brazilian Concretism, Lauand’s work is often uniquely characterised by a sensibility towards contradiction and poetic deviation. Forms are held in tension across the picture plane within mathematical linear structures, frequently destabilised and animated by decisive ruptures to her pattern.
