Forming a music ensemble is both an art and a science.It takes not only skill but some kind of psychic connection between the musicians to create on stage magic. The country's newest early music ensemble The Night Watch is about to put on its first concert - Love Me Tender - so it's a nervewracking time for the musicians especially as they'll only have a few days for the musicians and singers to rehearse together. Cellist Imogen Granwal is responsible for gathering together the early music specialists. We spoke to her and to one of the other members of the group soprana Pepe Becker.
