The beauty of the cello sound enriched with a sublime sense of humor, is the way quattrocelli reach the audience worldwide since 1997. Away from mainstream, the four gentlemen combine different musical genres into the experience of a unique and sophisticated classical entertainment. Their own point of view is the source of the fact, that the entire repertory of the quartet is especially arranged and composed for the ensemble. Lalo Schifrin, the composer of the track to "Mission Impossible", dedicated the piece "Crosscurrents" to quattrocelli, which was supported by the Siemens Foundation in 2008. During the international Rutesheim Cello Academy the opus was performed for the first time and broadcasted worldwide by Deutsche Welle DW. At the beginning of the quattrocelli story a grant from the Sellheim Society helped get things started with an important series of radio and TV performances. Invitations from all over the world followed. Among others, the group performed over 140 shows in the United States.As a frequent guest at festivals in all of Europe, the United States and Asia the quartet reaches the most different audiences by the diversity and high class of their performances. The energetic passion and unexpected musical surprises are an explosive mixture, which amuses, surprises and takes the listener into a world never expected by looking at a classical music instrument.
