A cheerful party-oriented folk music trio: Fredy Conrad (double bass, guitar, singing), Moreno Fontana (mandolin, guitars, accordion, singing) and Giorgio Valli (organetto, tres, singing). With the addition of a fourth member - Peo Mazza (vihuela, percussion, singing, first substitute incoming) - they become the largest 'trio' in the world. If necessary, Tri Per Dü also includes a mini-duo formation. All seasoned musicians who have been on the scene for several decades, in recent years they have appeared in successful broadcasts on the channels of the RSI Radiotelevisione della Svizzera italiana and on the SF Schweizer Fernsehen to arrive at popular national broadcasts such as "È tutta un'altra musica" and "Festa in piazza" on the Italian broadcasters of Telelombardia and Antenna 3. Also known to the public of Teleticino with the dialect program "Dimalami" for which they created the theme song and already nicely named "the best of the worst", they interpret in a very personal and very ' swing' the traditional cisalpine-insubrian repertoire, sprinkling a handful of ethnic sounds mixed with timbres with gypsy and Cuban-Latin flavours.
