"Helio Oiticica (1937-80) was one of the most creative artists of the twentieth century and played a key role in the development of Latin American art and culture. Since his premature death at the age of forty-three, his influence continues to grow. A key figure in the Tropicalia movement in Brazil that revolutionised popular music and the arts in the 1970s, he spent time in London and New York, where he forged new alliances and was a key influence on a wide range of artists.
Among his most important artistic achievements was the innovative and uncompromising use of colour that was a feature of his entire career, from his early abstract compositions to his later sculptures and large-scale installations. Combining it with music, rhythm and performance, he used colour to stimulate visual and tactile sensations, drawing in and involving his audience."
I'm feeling too tired/lazy to articulate my thoughts about Helio Oiticica's work today, so I've let the Tate website say it for me (better than I ever could).
