What is your opinion on Russian rock music?

No, it doesn't work. Do you see the difference between Amatory and As I Lay Dying? The first is alternative, and the second is metalcore. Or you can take Killswitch Engage as an example. Maybe it's considered one style, but the difference in quality is clearly visible.

Okay, think whatever you want (but Crossover Trash, MetalCore, and DeathCore are still alternative metal).

between Amatory and As I Lay Dying

If you compared our Ukrainian band TOL (Aggressive Nu-Metal) and As I Lay Dying, or our Ukrainian band Picture Inside Me (Melodic Death | MetalCore), I would say there is no difference, and the quality is the same for all. Well, is Amatory the only or the best representative of the heavy alternative scene?

The first is alternative, and the second is metalcore

I can say that the experimental direction (Death, Black, Doom) is bad, but there's no need to consider alternative to be bad...

There is also good alternative music in Russia, for example, Delfin....
