In the performance of this composition, volunteers carrying boomboxes and other music players parade through the streets of the participating city, presenting an ambient cacophony of recorded bells, harps, and electronic instruments composed by Kline.

[10][11] Throughout the performance, the audience (bystanders and participants) hear a soundscape of bells, harps, electronic instruments, and some references to Gregorian chant.

[20][21][22][16] After graduating from Columbia University in the early 1970s, Kline began his career in music, performing in and composing for art-punk groups such as Dark Day, The Del-Byzanteens, and the Glenn Branca Ensemble.

[23] In the early 1990s, pushing his avant-garde compositions further, Kline began creating tape-based sound installations for collections of boomboxes inspired by the work of Brian Eno, Steve Reich, and Glenn Branca.

[8][9] However, at the performances which Kline leads in-person (New York City and nearby locations), he still provides some early-arriving participants with vintage boomboxes from his own collection.
