Again no image - but we can imagine the sound

"The story of human kind could be narrated strictly through the history of musical instruments. Questions as to the when, where, how and why of their development amounts to the study of the rites and rituals that, taken as a whole, define human culture.

Reveille, the bugle call which signals the start of the military day, is the subject of Wake Up, a sound and light installation by the San Juan-based artist collaborative Jennifer Allora and Guillermo Calzadilla. ... their ongoing investigation into Vieques, an island formerly used as a bombing test site by the U.S. military... [is] ... a critique of socio-political agency in the face of increasingly remote authority.

In focusing on the trumpet, however, Wake Up has its genesis in Returning A Sound, a video in which the artists attached a trumpet to the exhaust pipe of a moped that was driven around Vieques by one of the island’s residents. A military call was replaced by the trumpet’s steady, shrill vibrato, its pitch changing with the moped’s speed. Returning A Sound was one amongst several works done and shown in Vieques. Some of the works were didactic, others involved Vieques residents."

(Figured out the link idea, finally!)

I'd love to have heard the trumpet on the moped exhaust - and the other sound explorations mentioned in Walker's article. Totally fascinating.
