This is the sound i heard every Friday lunchtime at school,where the whole class would move their chairs and desks in the direction of the exit to make ready for the rush to get to the dinner hall first before sport in the afternoon.
If scraping chairs,nails scratching down a blackboard,and general metal on metal friction is your gig,this is highly recommended.
