Electronic rock, also commonly referred to as electro-rock, digital rock, and synth-rock is the combination of electronic music integrated with traditional rock music. The creation of this relatively new music genre began in the 1950s and slowly progressed from there. However, it was not until the invention of MIDI, enabling many electronic instruments to be able to communicate with each other and let instruments to be played and recoded much easier and efficiently, when electronic music and electronic rock were fully integrated into the music scene. Synthesizers, electronic guitars, and guitar effects pedals, are just few of the primary inventions that helped electro-rock become what it is today.
