First time for everything.

[audience laughing] I don't know what that means.

I feel like there's a couple of things that usually needs to happen when a string band plays a set.

Uh, first, uh, tuning, check.

Uh, two, there should probably be a song somewhere that, uh, someone passes away.

Um, this feels like very into the string band song, uh, idiom.

Uh, thirdly, trains should be mentioned at some point.

Uh, people love trains.

It is named after our namesake.

We didn't name it after him.

I learned that tune many years ago and did not know that Dangerfield Newby was actually a, uh, Black abolitionist freedom fighter who fought at Harpers Ferry with John Brown.

And, um, it was meaningful to me to know that, in fact, we'd been paying some homage to a freedom fighter all this time, uh, who'd been making a place for us here in advance in the way that he could.

As you may have noticed, this is a Black string band.

- [Audience] Yes!

- Yeah, one person noticed.

[laughing] I didn't know.

This is such a progressive crowd.

[laughing] [applause and cheering] - With that in mind, folks, we're gonna play one last song for you.

Uh, this is an old blues tune, uh, that we like a lot.

Thank you so much for coming out to hear us tonight.
