L’Arpeggiata is a new music ensemble (or maybe a jazz ensemble) masquerading as a baroque ensemble. At the heart of this chameleon-like collection of inventive musicians is Pluhar. Leading the ensemble, theorbo in hands, she makes music that bridges epochs, treating centuries-old scores as points of departure. I first became familiar with her work through recordings, pausing and replaying passages over and over, amazed at what I heard. The virtuosity is awe-inspiring, but the way that she and her fellow travelers make those of us in the audience feel personally connected to the music unfolding before us is, perhaps, her greatest gift.
