The New Wave Of British Heavy Metal in my opinion has basically 2 eras.
The first era is from 1979 to 1981 which is considered the big boom of
Heavy Metal. The 2nd era is from 1982 to 1986-ish. So taking us into the
mid 80's a band from the U.K. emerged called Deep Switch. They looked
and sounded like no other band and that still holds true today. They
never really took heavy metal too seriously, but that doesn't mean their
music wasn't serious, because it was, although it was laced with a lot
of humor. I think Deep Switch was more influenced by Monty Python than
heavy metal. This is extremely unique and original material. Even if
you're not into obscure N.W.O.B.H.M., you should at least treat yourself
to hearing this just for the experience. The release consists of 2 CDs,
the first one being their classic album, while the 2nd disc is a
collection of all their demos. They had a very short lived career, but a
very long-winded tale of their history is written inside this massive
booklet along with ton of band photos. This band is so original and
unique I really couldn't even point you to some other similar sounding
bands.
