Question: Who is the uncle of Heidi Blomstedt?
Sentence (from "Jean Sibelius"): Sibelius composed prolifically until the mid-1920s, but after completing his Seventh Symphony (1924), the incidental music for "The Tempest" (1926) and the tone poem "Tapiola" (1926), he stopped producing major works in his last thirty years, a stunning and perplexing decline commonly referred to as "The Silence of Järvenpää", the location of his home.
