Symphonic Metal always throws people for a loop. Classically trained sopranos, often complete orchestras, or at least string sessions. (But then most people think Thrash Metal is all of Heavy Metal.) And despite all of that, there are plenty of screaming guitar riffs, and lots of drums.
This song is “Crimson Bow and Arrow” by Epica from the 2017 album Epica Vs Attack On Titan Songs. They are a Dutch Symphonic Metal band started by Mark Jansen after he left After Forever. (Though they do have a touch of Death Metal and Progressive Metal in some songs.)
