The Quarteto Radamés Gnattali will be embarking on a major tour of three Brazilian provinces - Acre in the far west, Mato Grosso in the central part of the country, and Piauí in the north-east. They'll be performing 15 educational concerts in some fairly small towns & cities, all based on arrangements of Villa-Lobos's Guia Pratico.
The model for this kind of tour is the 1931 Excursão Artistica Villa-Lobos, in which Villa and a group of musician friends (including Souza Lima, Nair Duarte and Antonieta Rudge) performed 54 concerts in the back woods of the states of São Paulo, Minas e Paraná. Things have changed a bit since 1931; I'm hoping that some YouTube videos will be posted during the 2009 tour.
Besides this huge undertaking, the Quarteto RG will also be performing all 17 Villa-Lobos string quartets at the Museu Villa-Lobos, on Aug. 12 & 13, 20 & 21, and 27 & 28. The group is taking the Ano Villa-Lobos seriously!
