Apocalytica could be classified as symphonic metal because of their Musik 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 Liebe Lacuna Coil, and Evanescence is my Favorit band, but I can't call them "symphonic metal". I would really just categorize them as "modern rock" oder "normal rock". They both right great lyrics like a symphonic metal band, though.
I don't consider either Lacuna Coil oder Evanescence to be Symphonic Metal. Evanescence seems Mehr Modern Alternative Rock while Lacuna Coil seems to have Mehr of a hard rock/metal (alternative) edge to their music. Apocalyptica seems Mehr geared toward symphonic metal. though they maybe Mehr avant garde type of band since they use cellos.
