The music business is like real estate. In real estate, location is the key, but in the music industry, networking is key.
You know you're successful at networking when you mention working for or meeting someone that the person says "oh really thats funny we've known each other for a while."
When you get a response like that, you're automatically in with that person and must be persistent in reaching out.
Everyone in the biz I meet, whether they're in PR or a Promotor, or a friggin Hospitality guy/girl, I make sure to let them know we'll be working together in the future, and I always email and set up a call or a meeting to just shoot the ish if the first opportunity was not long enough, or at the wrong place/wrong time.
You've got to stay in front of those you meet. Meeting people means nothing if you don't have the drive to form a relationship with them.
Relationships are everything. Money, music, and style won't get you anywhere. Relationships will.
Keep plugging.
You can definitely meet the people you need to.
