Gilberto Gil will perform at 8 p.m. May 16 at Hill Auditorium. Along with Caetano Veloso, guitarist and singer/songwriter Gil was a leader in the Tropicalia movement in Brazil in the late 1960s, a response to the military regime's censorship of songs and lyrics and its persecution of musicians, including Gil. Tropicalia blended native Brazilian folk music, such as bossa nova and samba with rock. Sponsored by the University Musical Society and Pfizer, 764-2538. (Photo courtesy University Musical Society)
