The Shack

In the beginning, KD, the Godfather of the Jam, created the "Shack". And he said, "Let there be loud music and liquid refreshment".
And it came to pass. And the bands that gathered there prospered and multiplied.
Well, their souls prospered and the equipment certainly multiplied.

So KD said to the assembled musicians, "Let us build a larger temple. Let it be in the spirit of the original, but let it be larger and of a more sturdy construction. And let it be environmentally friendly."

So the assembled multitude gathered bales of flax straw and constructed a building 40 cubits by 60 cubits, complete with stage and bar.
