At the Théâtre des Bouffes du Nord, the Diotima Quartet took up a challenge which is some kind of an achievement: play all 6 quartets written by Bartók in the same evening!
It is common to play these very demanding works over 2 or even 3 evenings, when played along with another composer, allowing to alternate (the Alban Berg Quartet had chosen Mozart at the TCE some years ago).
