Created in 2009 by Antonio Bonazzo, the groups leader, AB Quartet have since travelled around Europe playing their unique sound while perfecting their blend of genres and preparing for the launch of their debut studio album OUTSIDING (2017), a name that refers to the unconventional music themes and in general to the musicians and their individualistic style. The four diverse musicians that form AB Quartet, Antonio Bonazzo (Piano), Francesco Chiapperini (Clarinet & bass clarinet), Cristiano Da Ros (Double bass) and Fabrizio Carriero (Drums & percussion) all stand out in their own musical expertise but together bring something unforgettable to the music world playing a blend of classical, free jazz, jungle, rock and contemporary that leaves their listeners humming their tune for days. After the first album "Outsiding", recorded on 2016, in 2018 AB Quartet proposed "I bemolli sono blu" (Flat notes are blue), a review of some of the most intresting Debussys works played in the kaleidoscopic music style of ABQ to celebrate the 100th anniversary of the french composer's death. In 2023 they released their third album "DO ut Des" inspired by ancient music and in particular by Gregorian chant.
