ORIGINAL REPORT, SATURDAY MORNING: Some days back, we got a couple texts about someone with a full drum set, set up out in the parking area along Spokane Street under the West Seattle Bridge. We went by and saw the drums … but the drummer was nowhere in sight. Then we discovered via Twitter that Byron of BikeHugger.com had spotted the drummer one recent evening and recorded him. Byron gave us permission to use his video; he doesn’t know the mystery drummer’s backstory either. Do you?

ADDED MONDAY MORNING: Over the weekend, the “mystery drummer” identified himself in comments as Dakota Duran. In a followup chat by text during a break from his local grocery-store job, he told us that his band is Mad Culture, based in Admiral, and he drums under the bridge a few times a week so he doesn’t bother his neighbors.
