Though he was a contemporary of Mozart and Haydn, Boccherini's quartet repertoire shows a broader variety of influences--partly because Boccherini spent much of his working life in the mountains near Madrid, away from the strict Viennese fashions of the day, writing for the court of the exiled Spanish Infante Don Luis.
