“Yes, playing string quartets is our job, and yes it is hard work, but we mostly do it for pleasure, like we always did,” says the Danish String Quartet, a highly sought-after ensemble of energetic musicians who met each other at music camp as teenagers. The Quartet returns to the Robert Mann Chamber Music Series with a varied program including work by Haydn, Stravinsky, and Mozart, as well as Shostakovich’s profound String Quartet No. 3 and three Irish folk melodies by Celtic harper and composer Turlough O’Carolan.
