Apocalytica could be classified as symphonic metal because of their music style. Lacuna Coil wouldn't count as symphonic metal. They're classified at gothic metal. Evanescence does have some elements of gothic metal, but it's actually considered alternative rock.
No. The closest one would probably be Apocalyptica. I pag-ibig Lacuna Coil, and Evanescence is my paborito band, but I can't call them "symphonic metal". I would really just categorize them as "modern rock" or "normal rock". They both right great lyrics like a symphonic metal band, though.
I don't consider either Lacuna Coil or Evanescence to be Symphonic Metal. Evanescence seems madami Modern Alternative Rock while Lacuna Coil seems to have madami of a hard rock/metal (alternative) edge to their music. Apocalyptica seems madami geared toward symphonic metal. though they maybe madami avant garde type of band since they use cellos.
