Fernando Lopes-Graa was one of Portugals greatest composers of the 20th century, whose artistic credo was the binding together of the folk music of his native country with modern techniques to create an alternative and original national identity. With its constantly shifting tonal context the Divertimento perfectly captures Lopes-Graas inimitable style, which is further enriched in the concisely constructed Sinfonieta by his admiration for Haydn. The moving, even tragic Cinco Velhos Romances Portugueses are based on traditional ballads while the challenging Quatro Invenes, in the composers words, explore essentially atonal dramatic expressionism.
