The Koorbiënnale in Haarlem is a biannual festival, organized for the sixth time this year. The opening night consisted of four exciting modern pieces and the world premiere of a new work by the Latvian composer Ēriks Eŝenvalds. The first piece played was Daan Manneke’s Topos for chorus and harmonium. It is a song cycle set to four poems by Arthur Rimbaud.
