Liquid Trio is a young Catalan ensemble of improvised music which includes the eminent, world-famous pianist, Agustí Fernández. They have recorded three albums, the most recent of which, The Liquid Trio Plays Bernoulli, came out on the day of their concert at Ad Libitum. In the first half of 2017 in Barcelona, Liquid Trio joined forces with two excellent Polish musicians, trumpeter Artur Majewski and Rafał Mazur, who plays acoustic bass guitar. Both of them are well known to our festival’s fans. During this concert, the Polish-Catalan line-up played for the Warsaw audience for the first time.
