King's X is a critically acclaimed American hard rock band noted for its sophisticated music that combines progressive metal, grunge, funk and soul with vocal arrangements influenced by gospel, blues, and British Invasion pop groups.apart from the "grunge" I agree!

I'm listening to some of their records and they are really powerful!
I actually already knew some songs from Faith Hope Love (1990) and I already liked them, but also the other records are really pleasant to hear.

If you like power rock/metal, take a listen to this band!
Hope you enjoy it as I'm doing right now :-)
