About us

The Kölner Vokalsolisten (Cologne Vocal Soloists) are a six-part ensemble dedicated primarily to the vocal chamber music of the 20th and 21st centuries. They thereby set a focus that is unique for the Cologne region. The ensemble, founded in 2007 on the occasion of the performance of Luciano Berio's "Canticum novissimi testamenti," performed for the first time on May 3rd of that year at the MusikTriennale Köln under the direction of Marcus Creed.

After the MusikTriennale, performances followed at the festival Acht Brücken: Music for Cologne. The ensemble was also represented at festivals such as SchönesWochenende (Düsseldorf), the Mittelrheinfestival, the Cologne Early Music Festival and the Festa Paschalia. In 2015, the Kölner Vokalsolisten undertook their first major foreign tour to the Eilat Chamber Music Festival in Israel.

Their performance of Ernst Krenek's 80-minute a cappella work "Lamentatio Jeremiae" attracted much attention.

Classics such as György Ligeti's "Aventures", "Passaggio" and "Canticum" by Luciano Berio or "Rothko Chapel" by Morton Feldman form part of the ensemble's core repertoire. The Kölner Vokalsolisten collaborate closely with a number of composers and have performed many world premieres. A continuous artistic cooperation connects them with the composer and conductor Michael Ostrzyga.

The Kölner Vokalsolisten perform a wide range of vocal music dating from Guillaume de Machaut's Messe de Nostre Dame. Since 2014, they have presented their a cappella art in their own monthly lunchtime concert series ("Kölner Vokalsolisten am Mittag") at the Dominican Church of St. Andreas in Cologne. On the 24th of June 2017 a concert celebrating the 10th anniversary of the Cologne Vocal Soloists took place here. A concert to celebrate the 10th anniversary of the lunchtime concert series is planned for 25th June 2024.

The Kölner Vokalsolisten have performed with Ensemble Intercontemporain, Ensemble Musikfabrik and Ensemble Modern under the direction of conductors such as Pablo Heras-Casado, Enno Poppe, Duncan Ward and Philipp Ahmann. Radio recordings and interviews by the WDR (West German Radio) document the ensemble's work.

The two sopranos Natasha Goldberg and Theresa Klose joined the ensemble in 2021. Their participation has increased the proportion of early music in the repertoire.
