So what is FireRiffs?  FireRiffs are funny commentaries for movies, tv shows, and shorts.  If you’ve ever seen Mystery Science Theater 3000, Rifftrax, or Cinematic Titanic, that’s the kind of thing FireRiffs does.  Most riffs are MP3 files you sync up with the movie via simple instructions given at the beginning.
FireRiffs is written (with some exceptions) and performed by Scott Burke.
