I won't lie, I like heavy rock, and many sub-genres of metal. This last month, late on the game, as I've been told, I came across the Finnish symphonic metal band Nightwish.
Now, metal is not everyone's taste, for sure. It can be quite jarring for some, maybe even dramatically unpleasant for others. This band manages to blend symphony/operatic elements with pop and rock in an intriguing manner. What nailed it for me was the voice of their current singer, Floor Jansen.
I never regarded myself as an opera person, but I do appreciate a great voice. On 4th season of America's Got Talent, I was moved by Barbara Padilla performances. Likewise, I find myself moved by Floor Jansen's voice, and surprised to find it in a metal genre.
Not sure it's allowed to add Youtube links here, so if interested, do a search for Ghost Love Score Official on Youtube. It's a live recording from a 2013 concert in Wacken. Ms Jansen went through the range of voice control, head voice, chest voice, soft, aggressive, opera, valkerie. It was astonishing. Kudos to the whole band for the show. It must have been epic.
Tip: if Youtube ads annoy you, get the Ublock Origin extension. So much nicer experience.
