NME

NME, from Tacoma, Washington, formed in 1984, and unlike alot of other extreme bands of the era, their sound owed less to Venom than it did to the punk scene of the late 1970s and early 1980s.  Their sound, then, was a black/thrash with clear punk elements to it.  They released the demo Machine of War in 1985.

In its entirety, here is 1985's Machine of War demo

NME made waves with this demo, and the next year released the full-length studio album Unholy Death.  This is an album that has been cited by many in the black metal underground as being important and influential.  Unholy Death continues with the raw black/thrash sound found on the demo.

Off of the 1986 full-length Unholy Death, this is "Louder Than Hell"

After Unholy Death, one of the band members was arrested for murder and the band went on hiatus.  When they returned in the 1990s, their sound was pretty much thrash/crossover and the black metal elements were gone (or rather, with modern black metal in full swing, NME's sound didn't fit the mold).  I know one of the band members died in 2005, but I do not know the overall status of the band.
