Composer Frank Martin (1890-1974) and pianist Paul Badura Skoda (b. 1927) were musical soulmates and good friends. Frank Martin wrote two piano works for his Viennese viruoso friend in the last nine years of hi life: Concerto II pour et orchestre (1968/69) and Fantasie sur des rythmes flamenco for piano solo (1973). Both works were created in a unique cooperation between composer and pianist that can only exist when people are good friends and have complete trust in each other's musical integrity.
