queen. anybody who harmonises solos, is almost certain to be compared to brian may of queen.

some examples of bands harmonising are bruce dickinson/iron maiden. BD, who i actually own an album from, has one guitar tuned to standard E (E A D G B E) and one to standard A (A D G C E A). this is cool because it enables a very low sound but melodic at the same time.

also, with the first example that john showed, amon amarth do that alot on their first album, once sent from the golden hall.
