Written by a composer long immersed in new and experimental music, this book provides a tour of the music, technologies and people that have transformed how we make, hear and think about sound over the past fifty years.

As both a participant and critical observer in the post-Cagean musical landscape, Nicolas Collins uses anecdotes and analysis to survey the history and aesthetics of the musical avant-garde. Among the topics explored are: relationships between popular culture and the avant-garde; the shifting definitions of improvisation and composition in a world where musical scores might take form as charts, drawings, words, notes written on a staff or electronic circuits; the social and aesthetic effects of analog and digital resources in the production and consumption of music; and more broadly, the nature of experimental thinking in creative pursuits.

The book follows a personal chronology of observations and experiences with music, technology, economics and culture—from youthful encounters with John Cage and Minimalism, to the Downtown and East Village scenes of the 1980s, the assimilation of avant-garde sensibilities into European concert halls and global pop, the burgeoning of sound art, and the transformative influence of digital technologies both positive and negative.
