finding out about music conferences in major cities?

I'm trying to find opportunities to network outside the web and I was wondering how could I find out about music conferences in major cities? How do I find out the contact info of record labels?

Try networking at a "lower" level first...i.e- music stores...Generally hip hop- vinyl based...if you know what i mean...Usually your underground stores tend to know whats crackin more then General population shops. Although alot of these works in underground music stores tend to talk alot of smack (trust, i know) they usually do hear the word on the street thru peeps comin in and out of the shop on the daily grind. Most 'major' labels dont tend to doconferences like they use to, now the worlds gone digital and shit, most labels scout around on Myspace and all that.....
