The Lassus Quartett (Basel, Switzerland) has appeared in festivals and concert halls in Portugal, Spain, England, Switzerland, France, Norway, Belgium, and Germany. They are coached regularly by members of the Hagen Quartett, in particular Rainer Schmidt, the Cuarteto Casals, the Alban Berg Quartet, and the Artemis Quartet, and have also been influenced by Rita Wagner, Rohan de Saram, and Clive Brown. Comprised of a Catalan, a Spaniard, an Englishman, and a Canadian/German, they consider themselves to be united through humanity, friendship, and art, carefully curating programs that explore a wide range of repertoire, from works by Hildegard of Bingen, Haydn, and Beethoven, to compositions of the modern age, often by living composers. They frequently collaborate with poets, dancers, actors, and visual artists, and sometimes sing as a choir. Their recently released album features the music of Sciarrino and Ockeghem was recorded in an old wooden church by the fjords of Norway and is accompanied by the film "Music in Silence", which documents their choice to forgo all verbal communication during their recording process. Upcoming performances include Feldman's second string quartet, a performance installation lasting five hours, and a new album with their arrangement of the Orlando Lassus iconoclastic Prophetiae Sibyllarum.
