I was blown away the first time I heard Hex. It was so familiar, yet completely different. When Cheat the Gallows came out, I got it immediatley but was a little let down with it. It didn't grab me by the short & curlies like I hoped it would. I've since warmed up to it a little more, but it'll never compare to the first spin of Hex.
I'd like to hear their back catalog, but it all seems out of print & a little pricey for me. Some day I'll track it down.
