It's a practical joke Sambo. The poor woman is being woken up by the sound of a Death Metal band called 'Cannibal Corpse'!
I had a look at their live video from that you tube page. They sound like a wheelbarrow full of hardcore being tipped into an empty skip on repeat and a seal lion with tonsilitis squawking randomly over the top after being put through a pitch shifter down 2 octaves. :?
