Present on the music scene for more than fifteen years, the Ápeiron Guitar Quartet (AGQ) conducts its concert activity aimed at the discovery and disclosure of the original repertoire for four guitars, inspiring and motivating the composers to write for this ensemble. In 2006, they produced the first album “Ápeiron” with music composed by York, Duarate, Brouwer, Laurent, Miletic, Rak and Bellinati. In 2010, the quartet took part in making of the CD “Playing Marcos Vinicius”, which was published by Sonitus. AGQ has also been recorded and broadcasted by Rai 3 and Czech National Nadio. Furthermore, the quartet has established several notable collaborations with composers such as Ivan Šuran, Desmond Clarke, Paul Mortilla and Daniel Kessner. In 2013, AGQ participated at the XXVI Guitar Congress in Sanremo , Italy. The following 2014 and 2015, as quartet-in-residence, they premiered several works at the Highscore Music Festival in Pavia where the guests of honor were Steven Mackey and Helmut Lachenmann.
