This week in the fishwrap, new contributor P. Nick Curran takes the pulse of a burgeoning neo-folk scene congregating monthly, sans amplification, at an undisclosed location in Allston.

We've got three clips: one (above) of Old Hannah, one of Beaven, and a quick sketch of the most recent Hoot, which transpired on March 27.
