what are the best sites to find out about monthly events happening at Las Vegas nightclubs?

I am looking for a website that will give information about weekly and monthly events happening at nightclubs in Las Vegas. I have tried looking at the typical sites such as lasvegas.com and although it is a good informational site, it does not have information about events happening at the clubs on a monthly basis. I will be going to Vegas next week and I want to find out what events are happening each night at all of the clubs while I am there. thanks
Joe S …. did you even bother reading my question? I clearly said that I am aware of sites like Vegas.com. That site offers good information about the clubs, but they DO NOT offer ANY information about the nightly events taking place at the clubs.
