“Angústia e Folia” is a piece using only percussion instruments whose instrumentation is traditionally associated with Brazilian musical practices. It explores the contrast between contraction and expansion through musical gestures: long notes gradually become shorter and more widely spaced, while initially spaced notes progressively come closer together until forming a continuous sound. The title is a wordplay on the scientific name of the araucaria tree — Araucaria angustifolia — native to southern Brazil. From angustifolia emerge the words “angústia” (anguish) and “folia” (revelry).
