The Kammerorchester Basel ("Basel Chamber Orchestra") has inherited a long tradition of small-ensemble music-making in the Swiss city of Basel, cultivating a twin focus on early music and contemporary music. It performs music up to the Classical period on historically appropriate instruments. The group won an ECHO Klassik Ensemble of the Year award in 2008. A notable Kammerorchester Basel recording was a 2011 set of Bach cantatas performed by countertenor Andreas Scholl. The year 2017 saw the release of a recording of music from Bologna in the year 1666. Kammerorchester Basel performs at the Olten Stadttheater in Basel. Under Giovanni Antonini, it began a project to record all of Joseph Haydn's symphonies together with the orchestra Il Giardino Armonico; the cycle is set to conclude in 2032. In 2022, Kammerorchester Basel backed soprano Giulia Semenzato on the album Angelica Diabolica.
