Noisy Neighbors

[kimmercake.livejournal.com]

Need your help with an awful noisy neighbor problem -

I have called the police for noise complaints too many times to count, these people will not stop their music blasting and rager parties. Sometimes the police show up, sometimes not. They party in their backyard so the noise can be heard on all sides. I, quite frankly, can't believe there aren't more complaints. These people are awful. I'm wondering what my options are in terms of next steps. I'd love to contact their landlord but have no idea who that is or how to find out (most people own in our neighborhood). Can I file an official complaint with the city somehow? I've also filed complaints on these people because they leave food and garbage out for days after their parties and I'm worried about rats. Ugh. Any help would be much appreciated.
