Enter Shikari formed in 1999 under the name Hybryd before adopting their final name and lineup early in 2003. The group began blending heavy guitar riffs with electronic textures during the early 2000s to create a sound critics later labeled electronicore.
Electronicore combines distorted guitars, sequencers, auto-tuned vocals, and screamed passages to create stark contrasts within rhythmic patterns. Bands utilize dynamic transitions that move listeners from soft electronica ballads into intense metalcore breakdowns without warning.
