Megadeth - A house divided... This song has very cool trumpet intro and outro which reminds of musical pieces that a lot of old western movies used in them.
Poisonous shadows. There you can hear some violins and piano. btw This song is from the last album Dystopia. So definitely listen to it as soon as you can xD
You definitely need to listen to Steven by Alice Cooper. Actually, the whole Welcome to my Nightmare album. If you want orchestra, well this was huge when I was growing up.
Isn't Megadeth but is Megadeth related before Marty Friedman joined with Megadeth he also played with Jason Becker on an album called speed metal Symphony cacophony look it up elements are very strong very full and concise music for matured metal ears only, quick slip and Skip rhythms are all included. My personal favorite and in my opinion highlight song on of the album is THE NINJA
Well, try out the song "Closer" by the brand new band #Clockwork. They're a power metal band with, count 'em FOUR vocalists. Two male, two female. And they have a keyboardist so there's a bit of that symphonic element in it.
