The New Wave Of British Heavy Metal covers a wide range of styles. From the more traditional heavy metal of Iron Maiden and Tygers Of Pan Tang, to the doomy Sabbath inspired Angel Witch, and the more fast and punky Raven. Then there is Demon, who have more of a 70's rock sound...possibly drawing a bit on Blue Oyster Cult for influences. Not a sound that I'd associate with the NWOBHM, but still, Demon were a British band in the early 80's, so they fall under the NWOBHM umbrella.
The Unexpected Guest was released in 1982, and is Demon's second album. I've heard that the band get a bit more weird and progressive after this record, so all I've ever listed to has been this one and their debut,
Night Of The Demon. Both are great rockers.
This was another record that I grabbed from my favorite seller on eBay at the moment. His old metal records are in great condition and start with a nice low starting bid... I assume that not many people bother with eBay much these days for records, so I've been lucky to win a number of things from him at a low price. His latest auctions haven't interested me too much, so I wonder if he is hitting the bottom of what he was looking to sell. If this is the end of his good stuff, it has been a great run this year.
Demon apparently were a bit theatric with their live stage show, and it is cool to have a bit of that captured on the inside of the gatefold sleeve.
Demon are a strange fit in the NWOBHM as their debut, Night Of The Demon, feels a bit dated for its 1981 release. It feels like it crawled out of the mid 70's and fits better alongside more straight forward rock bands like Kiss, instead of the frantic energy of Iron Maiden and Raven... and because of this I kind of dismiss them and rarely take them out for a spin these days. 
I do still really dig the first two Demon albums (even though I tend to enjoy The Unexpected Guest quite a bit more), so when Jeff quoted me a price for Night Of The Demon I figured that I might as well add it to the collection.
