This is absolutely amazing! Available in April 2006, the Invisible-5 Audio Project is “a two-CD, self-guided audio tour along Interstate 5 between Los Angeles and San Francisco. It uses the format of a museum audio tour to guide the listener along the highway landscape.”
Available now as an appetizer is the audio tour for Bayview Hunters Point / San Francisco.
One is forced to wish for a similar set for the entire American interstate highway system and navigable waters. Tocqueville x Steinbeck x Huckleberry Finn on your iPod. Or even for the New Grand Asian Silk Road. As recorded by Walter Hood because I dig his quasi-James Earl Jones timbre.
