It's the reward for the £19 tier of the PledgeMusic campaign, which I backed pretty much as soon as it went live. That included a digital download of the album as soon as it was released, but it's really nice to actually have a physical copy now. Also, there's the bonus disc, which as usual is about as good as the actual album.
The campaign was actually something like 600% of the target by the end of it, with most of the excess going to fund Devin's next Ziltoid album, along with donations to charity, so that's really cool too. Devin has great fans, and he deserves to.
