“The Amsterdam Concertgebouw has announced that [conductor] Fabio Luisi has been forced to cancel his Christmas Matinee concert with the orchestra having tested positive for Covid-19, requiring him to quarantine for ten days,” writes Susan Elliott in Friday’s (12/18) Musical America (subscription required). “Klaus Mäkelä, 24, … will step in for Luisi. The program has been changed as well, to Beethoven’s Pastoral Symphony and Debussy’s La mer. The Christmas Matinee is broadcast by AVROTROS on 25 December via Dutch national radio station NPO Radio 4 (at 2 p.m. CET) and on television via NPO2 (at 3 p.m. CET). Outside the Netherlands, the concert is streamed on 26 December through https://www.concertgebouworkest.nl/en/watch-listen. Queries as to Luisi’s health have not yet been answered either by the Dallas Symphony, of which he is music director, or the Concertgebouw.”
