During the 1980s, several thrash metal and death metal bands formed a prototype for black metal. This so-called first wave included bands such as Venom, Bathory, Mercyful Fate, Hellhammer and Celtic Frost. A second wave arose in the early 1990s, spearheaded by Norwegian bands such as Mayhem, Darkthrone, Burzum, Immortal, Emperor, Satyricon and Gorgoroth. The early Norwegian black metal scene developed the style of their forebears into a distinct genre. Norwegian-inspired black metal scenes emerged throughout Europe and North America, although some other scenes developed their own styles independently. Some prominent Swedish bands spawned during this second wave, such as Marduk, Nifelheim and Dark Funeral.
As summarized by product review website Wirecutter in 2018, Speed Queen’s top-loader washing machines have a reputation for being “wasteful [and] ineffective”, requiring much more energy and water than modern front-loading washers, however on the other hand are regarded as “exceptionally durable and repairable”, with fans also praising their ability to thoroughly clean heavily soiled work clothes. A 2018 design change introduced what the company described as a “radically different” washing mechanism, abandoning the separate movement of agitator and tub for which Speed Queen laundry machines had hitherto been known. The 2018 design of the TR7 review received a “poor” rating by Consumer Reports for cleaning clothes–the only washer tested by CR to receive such a rating. On the “heavy cycle” CR said the cleaning rating would be “fair”.
