I'll start with Rachel Podger, the HIP baroque violinist. I've seen her twice now - each time at Norwich Cathedral, playing with Norwich Baroque - and she is amazing. Not just as a player, but as a person - she is so warm and lively that she inspires all around her, so that Norwich Baroque have responded with passion and sounded their very best.
Rachel went into the pulpit both times, and sounded like an angel as she played some Bach that she'd arranged for solo violin.
