Catherine Bott explores the themes of the 2009 York Early Music Festival from the National Centre for Early Music. The UK's largest festival of early music takes its inspiration from the anniversary celebrations of Purcell, Handel and Haydn and looks at lifelines, from the medieval to the Baroque. With a mixture of music and conversation, Catherine meets some of those involved in the festival and introduces live performances from the Cambridge-based Clerks Group and Edward Wickham, the Danish ensemble Baroque Fever and, from Italy, Fabio Bonizzoni and Emanuela Galli from the group La Risonanza.
