MASSFILC is a 501(c)(3) corporation, based in Massachusetts, created to promote filk music. It was originally called M.A.S.S. F.I.L.C., but the name was changed in 2010 to be less confusing to the state. It sponsors the ConCertino convention, has published filk books, and occasionally helps local conventions with filk programming.
