Uncertain and mysterious remain the origin and the musical formation of Giuseppe Demachi (1732-1791), a composer that is rather well known in Europe for having published many works in Geneva, Lione, Paris and London. The works published by Demachi known so far are 17, four of which are violin concertos, but others appeared without indication of opus number, and others still remain hand-written, two of which are programme symphonies entitled 'Le Campane di Roma' and 'Il corso del giorno alla Campagna'. The compositional skill that led him to fame was not second to that of performer: the intense concert activity forced him through the courts of all Europe, where he was highly appreciated. The ensemble Trigono Armonico led by Maurizio Cadossi performs a vast anthology of his chamber music on period instruments and in full respect of the philological practice.
