Subterranean sounds
Since my column mentions the subway performers I saw while in NYC, and I have photos, I might as well share them here as a bonus. (You can read more about NYC subway performers at the Saw Lady's blog.)

Above are the Ebony Hillbillies in (I think) the 42nd Street subway station, doing old-timey songs such as "Hard Times." There was a decent-sized audience, as seen below.


Speaking of old-time sounds, how about this fellow on musical saw? I think he was in the Rockefeller Center station. He was performing some recognizable pop chestnut that had me humming, although the title has since slipped my mind.

There are urban entertainers galore most days at Venice Beach. A different breed, perhaps, but entertaining nonetheless.

I try to make sure I have a few small bills and coins with me when I'm lucky enough to make it to Venice. The musicians and the junk food are what make the trip worthwhile.
GREETINGS:
The problem with saw players is they are hard to see. And while many are long in the tooth, their music, typically, is cutting edge.
Sorry, I just couldn't resist!
[I'm surprised you didn't say that the instrument makes you so sleepy, you start sawing logs. -- DA]
Just a tidbit -- Dodger catcher Russell Martin was raised in Canada by his father, who made his living as a street musician like this. I really do love rags to riches stories.
