A Busman’s Holiday performance begins with the thump of kick-pedal on suitcase and the tuning of acoustic guitar strings, two affable brothers quietly considering where to take their audience first. They may begin with an exultant and driving harmony or a ballad in a melancholy mode, but not before they have laughed and shared stories with their audience, patient and cheerful, assuring the crowd that they are in good hands. As Lewis and Addison begin to sing, their voices together evoke the Southern Indiana where their music was born. One can’t help but feel the presence of the songs’ characters in the room beside you, the music offering intimate details from vivid strangers.
