Though best known as a musicologist - the author of 16 books - Lawrence Kramer's other life as a composer shines through all his writings. He says he has become increasingly aware that music is made of sound, a fact that in Kramer's view has perhaps been 'too obvious for its own good'. Accordingly, he has turned his attention to writing about the nature of sound and ways in which we perceive it, first in The Hum of the World and now in Experiencing Sound: The Sensation of Being. We welcome him back to The Music Show to discuss everything from Martian winds to Bing Crosby singing 'White Christmas'.
