The conductor Jeffrey Tate once described the string quartet as ‘the most perfect expression of human behaviour’. Composers from Haydn to Adès have revelled in this most intimate and virtuosic of musical forms, awed by the sight of four musicians moving across a tightrope at speed.

This prizewinning Berlin-based quartet has gathered fans aplenty across Europe since forming in 2012, and here makes its thrilling Australian debut.
