Protean Quartet

String Quartet on period Instruments

“One of the most fascinating, exceptional and captivating quartets of our generation with an unique

and innovative approach to music”- David Greilsammer, conductor& pianist

“not only they play brillantly on period instruments but with a
very singular way full of carisma”.-
Francisco Lopez, soloist from Oslo Philharmonic

"... The conceptual firmness, their sound, the management of colors or the impeccable work in the low dynamics are some of the wicks that the Protean Quartet presented here, demonstrating that they are one of the most interesting groups on the international scene dedicated to historically informed performance"... -CODALARIO Magazine

The Protean Quartet is born in 2018 in Basel, moved by the curiosity and passion for the “Historically Informed Practice” movement. The ensemble is mainly focused on the rediscovery of the stylistic, rhetorical and technical aspect of the musical language from the Classical and Pre-Romantic period. The deep interest in the combination of authenticity and meaningfulness, aims to establish a fresher musical speech style.

Graduated in several european Colleges of Music (Berlin, Zürich, Frankfurt, Basel), their members have been strongly influenced by diverse artists such as Amandine Beyer, Roel Dieltiens, Olivier Foures, Christophe Coin, Andrea Marcon, Jörg-Andreas Bötticher, Thomas Demenga, Paolo Pandolfo, Petra Müllejans, Ferenc Rados, Anton Kernjak, Claudio Martinez -Mehner, Eberhard Feltz, Rainer Schmidt and the Quartets Casals and Quiroga.

Since its formation, it has performed in important festivals in Spain, Germany and Switzerland, including the Oude Muziek Festival in Utrecht 2019 (Groote Zaal, Tivoli Vrendeburg) FIAS 2021& 2022, Festival de Saintes 2021, York Early Music Festival 2022 & 2023.
Recently, Protean Quartet has been awarded the First Prize at the Biagio-Marini International Competition 2020 and York Early Music International Competition 2022, signing for a new CD production by the top label Linn Records.

In Fall 2022, their debut CD is coming out with Eudora Records.
