Before we had the gods of Metal Metallica, we were treated with a hardcore debut album from Diamond Head. This album, released for the first time back in 1981, and was the first of many speed metal albums i have added to my collection over the years. These guys have more riffs in one song than Black sabbath have on an entire album. The riffs are the most stand out part of this album, being fast and heavy, and extremely hard to play. A few track favourites are all of them. This is the kind of album you can put on and listen from start to finish, without once even thinking of skipping a track. If you are new to the genre, or have been a long time fan, then I suggest you stop anything your doing and order this album from Amazon.com, you won't regret it, that's a personal guarantee. I would have given it more than five stars out of five, but they don't have that option.
