The NPR "Tiny Desk Concerts" feature musicians performing in the NPR Washington DC office. This is the first production by one of the NPR interns, of a band of 8th graders who've been playing together for 5 years and who sound at least 5 years older.
It's not folk, but it is acoustic... "indie" is the label in this case, I guess.
