[EX Q]: An exellent study of the German Airforce from the fall of Sevastopol in the Crimea to its failure at Stalingrad. Very well written, with a clear analysis of the events. Well worth the money and it belongs in every major collection on World War II's Eastern Front.
[EX A]: Positive

[EX Q]: I've read several other Deborah Smith books. In my opinion Blue Willow was the best. Sweet Hush was by far the corniest book, I've read in a long time. The phrase "Sweet Hush" must have been at used at least 100 times in the book. The main character "Hush" was predictable and one dimentional. If you enjoy Deborah Smith books, I would skip this one.
[EX A]: Negative

[EX Q]: Like the famousMetal Massacre, Vol. 1, which is noteworthy for introducing the world to Metallica, Metal Massacre III's major claim to fame is that it unleashed thrash legends Slayer.The early Metal Massacre compilations are the best reflection of the American metal scene at the time, as such this 1983 release is full of power, traditional, and proto-thrash metal bands that are all clearly influenced by the NWOBHM scene. In addition to some of the "name" bands like Slayer, Virgin Steele, and Bitch, Metal Massacre III featured bands like Snowhite (later Znowhite) and Warlord that developed a cult following, as well Medusa, Test Pattern, Sexist, Marauder, and La Mort, who appear only on this album and were never heard from again.A lot of these bands and songs are raw and unpolished, but that was part of the charm of the early 80's metal scene. These Metal Massacre albums are a great way to revisit that era, and are a must-have for all old-school metalheads.
