What used to be rock in the 1950s has changed in itself over the years. Rock used to basically just be 2 guitars one playing rythm and the other playing the melody. Along with a base and drums. The classic rock sound was not has hardcore as it is today.
Even though rock has essentially stayed true to its general instruments. Its sound has changed drasticly. Using more electric and syncronized sounds. Distortion has become one of the most popular styles of guitar in todays rock. Changing the sound of the guitar to give it a rougher edge and tone.
The most hardcore form of rock today would probably have to be Heavy or Death Metal. Where the chords are usually so distorted that you can barely even tell the difference between chords. And the singers usually scream the lyrics into the microphones. This is supposed to show the emotion behind the words.
