Matt Jalbert's Rockin' Out, San Gabriel Mountains.

Matt takes "Photographs of the bizarre, the unusual, the sublime, and the beautiful found in my travels through the deserts of California and Nevada." This particular one is captioned:

Along Angeles Crest Highway in Los Angeles County’s San Gabriel Mountains, I came across this man playing drums. He set himself up at the edge of the road, overlooking a vast canyon through which his drums echoed, and beat along to the music playing through his headphones. As I was making the photograph, an emergency truck sped by, sirens blaring — cacophony shatters the mountains’ silence.
