Performance by Kenyon Adams and Jonny Rodgers »

Rockfall is the geologic term for the falling, rolling, bounding, or tumbling of a newly detached mass of rock from a cliff. That a rockfall had recently occurred was apparent as soon as we entered the Box Canyon. Several fresh boulders gleamed conspicuously from the dark canyon floor. Elsewhere, piles of white rubble marked where other falling rocks had shattered on impact. We all looked up in an effort to identify the source. And also to be sure nothing else might be headed down soon.

So it seemed altogether appropriate that Kenyon and Jonny had planned to try the blues standard, “Rollin’ and Tumblin’.” They took up seats on a couple of these new rocks and, after a quick refresher of the progression, initiated the Box Canyon blues.
