Studies exoticism in Post-War popular music. This work analyses the work of Les Baxter, Korla Pandit and Yma Sumac - the musicians who developed the style known as Exotica in the 1950s and 1960s. It also addresses more recent developments in musical exoticism which have revived and reflected the form, such as the career of New Age populist Yanni.

During the 1950s and early 1960s, the musical exotica produced by performers such as Les Baxter, Martin Denny, and Arthur Lyman enjoyed international success. Widening the Horizon is the first in-depth analysis of the music and its cultural context.
