A friend and I made the expedition to the Hendrix College campus to see this:
A little background: Hendrix College has outgrown its original campus, expanding across a busy roadway. After endless and disruptive construction, the city of Conway now has a huge double roundabout with a tunnel beneath it, allowing students to cross to the health and wellness facility and The Village at Hendrix, .www.hendrix.edu/Village/village.aspx.
A tunnel beneath a street does not sound inviting, but this is rather enchanting. A visit to www.janneysound.com is worthwhile. Harmonic Fugue is a permanent installation.
