Protean Quartet
Since 2018, we have focused our activity on historical performance on period instruments. Our proposal, focused mainly on music from the Baroque to the Romantic period, involves both for us and for the audience a rediscovery of that languages in technical, stylistic and rhetorical terms, thus offering the creation of a new musical discourse both individually and as a group.

We are Javier Aguilar, Edi Kotler, Ricardo Gil and Clara Rada. We have studied in Berlin (Universität der Kunste and Hochschule für Musik “Hanns Eisler”) and Basel (Schola Cantorum Basiliensis).

We engage in a dialogue with the audience through enthusiasm, passion, responsibility and authenticity. Therefore, we consider it a necessity that the string quartet, as an instrument of communication, must possess a critical and historically interpretative spirit. It goes without saying that one of our main creative engines is the recovery of Spanish music heritage and its dissemination.

Throughout these years, we have performed at the Festival Oude Muziek in Utrecht (The Netherlands), the Festival de Saintes – Abbaye aux Dames (France) or the Festival Internacional de Arte Sacro (Spain), among others. In 2020 and 2022, respectively, we won the first prize in the International Early Music Competition “Biagio Marini” (Germany) and in the “York Early Music International Competition” (United Kingdom), organized by the NCEM (National Centre for Early Music).
