I wouldn't normally mention a music documentary here, especially as I have absolutely no idea who Subsource are or what 'dub-punk' sounds like. However, Subsource: A Dubumentary is worth noting as it has been made by Colin Arnold, producer of the marvellous The Fallow Field.
Here's Colin's production company website and here's the trailer for the 'dubumentary'. the DVD is out next Monday from Left Films.
The Fallow Field, which was scheduled for a September release from Left Films, will now hit the shelves in January via Monster Pictures.
