Awesome guitarists (both playing and arranging are top-notch) and awesome lead singers (unique voice, the best weapon to sing hard rock and heavy metals), such a band is once in a century, and it is no exaggeration to say that it is the peak representative of rock music.

Guitarists in some top bands can compete with ACDC, but the lead singer is much inferior. Rock lead singers who can compete with ACDC lead singers are also rare. Steven Taylor of The Blacksmith in the Air is one of them, but the guitarist of The Blacksmith in the Air is not as good as the guitarist of ACDC.

The conclusion is that the combination of an excellent guitarist and an excellent lead singer like ACDC is rare in the world.
