What type of music do you listen to?

It's a genre that was mostly in Britain (obviously) and the NWOBHM bands released their first mostly in the late 70's and early 80's. The name comes from the fact that in the 70's punk was very popular in Britain and heavy metal was mostly forgotten except for the big names like Black Sabbath, Ufo, Led Zeppelin etc. and even they weren't doing that good. Then suddenly most notably bands such as Iron Maiden and Def Leppard started getting record deals and heavy metal started getting more popular again. Bands like Angel Witch, Diamond Head, Grim Reaper and Tygers Of Pan Tang are the most NWOBHM-sounding bands there are in my opinion. Just listen to their earliest records and you should get a pretty good image about what traditional NWOBHM sounds like. Especially listen to their first albums, Angel Witch self-titled, Diamond Head's Lightning To The Nations, Grim Reaper's Welcome To Hell and Tygers Of Pan Tang's Wild Cat. Some tracks from every one of those albums are on YouTube so it's easy to check them out. Despite the name that refers to Britain, there are also some NWOBHM bands that aren't actually british, for example the swedish E.F. Band. More information about NWOBHM (most importantly a huge list of NWOBHM-bands) can be found at a site called www.nwobhm.info Hopefully this helps and you now know what NWOBHM means
