From the Yahoo Group: "Firefilk is an international brand of music written by fans of Joss Whedon's Firefly and Serenity 'verse. Some of it is funny, some serious, some completely original, and some covers of already established music from the series. All of it showing a love of the universe that brought Browncoats (Firefly/Serenity fans)from around the world together into one great community. Whether you're a Browncoat or just a fan of Filk, you will love this music. It is evident in the music that there is a true love of the source material by the talent behind it.
In most recent news, the Signal recently released a compilation of their featured Firefilk at http://signal.serenityfirefly.com/shownotes.php?e=2240
