In 2002 Caetano Veloso published an account of the Tropicália movement, "Tropical Truth: A Story of Music and Revolution in Brazil". The 1999 compilation "Tropicália Essentials", featuring songs by Gilberto Gil, Caetano Veloso, Gal Costa, Tom Zé, and Os Mutantes, is an introduction to the style. Other compilations include "The Tropicalia Style" (1996), "Tropicália 30 Anos" (1997), "Tropicalia: Millennium" (1999), "Tropicalia: Gold" (2002), and "Novo Millennium: Tropicalia" (2005). Yet another compilation, "Tropicalia: A Brazilian Revolution In Sound", was released to acclaim in 2006.
