C & D’d is a mellow, upbeat instrumental song. That twangy sound is a (fake) berimbau, a percussive string instrument.
I’ve been listening to the songs on Metafilter Music – all the songs! – from the very beginning. On weekday mornings, I’ll add a song I like to this – it’s a song of the day podcast.
I'm Pronoiac at Metafilter, Twitter, and Gmail.
