To mark their 525th Anniversary, the Vienna Boys Choir tells its history in music, with all of its choirs singing: the boys' choirs, the girls' choir, the mixed children's Chorus Primus, the youth chorus Chorus Juventus, and Chorus Viennensis, the choir of 'old boys'. 14 fabulous instrumentalists join in the music. Together, they show how an Imperial choir consisting of a handful of boys becomes an entire singing campus. The Vienna Boys Choir, known for its polished artistry, robust sound, and ebullient charm, is probably the most famous boys' choir in the world. More than 1000 tours in over 100 different countries attest to its global fame. Between them, the four groups making up the Vienna Boys Choir sing almost 300 concerts per year, reaching half a million people live. 2023 marks their 525th anniversary, and Universal Music joins in the celebration.
