Grindcore is loud and fast music that makes you feel like you're riding on a very shaky rollercoaster. The music usually has very short songs that are less than a minute long which means you don't have to wait for very long to listen to the whole song.
Grindcore is like a musical game of tag. The singer screams into the microphone and the drummer plays the drums as fast and as hard as possible like they are trying to catch each other. The guitar and bass usually just play really fast and loud so you can barely hear them over the screaming and drums.
Grindcore also looks like a scary monster with crazy artwork on the album cover that looks like it's coming to life. The lyrics talk about really heavy topics like death, violence and politics, which are usually hard to understand because the singer is shouting so loud.
In summary, grindcore is fast, loud, full of screaming and difficult to understand lyrics. It's like playing tag with instruments while being on a scary rollercoaster!
