Styx

This is what Styx singer, James Young, had to say about Evanescence:

Question: I know you tour regularly with REO Speedwagon, but if you could tour with one band who would it be?

Answer: Evanescence is a band that sounds a lot like Styx. They do a lot the things that made us successful — harmony vocals with heavy guitar underpinnings. They sold four million records, but like us, don't get critical praise. When Creed was together, I thought they had a sense of melody, but the power of guitars were still there. There's two for you.
