Anne Hero sort of sounds like Botch on speed. You'll hear tons chugging guitars followed up by those screeching alarm clock sounding notes. The songs are extremely short and seem to put as much tension and chaos into the shortest amount of time possible.
The short run time and chaotic feel sort of throws an Orchid influence into the mix. The screeching vocals also emphasize the chaos very well. They end things with a very dreamy clean guitar part that whirls with finger tapped notes.
About three minutes total of music, but definitely no slouch.
