Itibere Zwarg is an award-winning Brazilian bassist and the longest-serving member of Hermeto Pascoal’s ground-breaking ensemble ‘O Grupo’.Since their first meeting in 1977, the two have been closely collaborating to create a unique musical language: a genre-defying polyharmonic, polyrhythmic music, now widely studied by musicians and musicologists alike, known as ‘Universal Music’. Back in 2001, Itibere led a workshop at Villa Lobos School of Music, with twenty-nine of Rio de Janeiro’s most exceptionally talented young musicians. The result was Pedra do Espia, an Amazonian orchestral masterpiece which is as difficult to categorise as it is fun to listen to. The record harnesses the pure creativity of youth and nature, creating a magical sense of innocence amongst the striking compositions and astonishing musicianship.
