In the New Rockstar Philosophy Book we have a good section on making friends. The more you get into this industry the more you realize how important making friends is. But making connections outside of your industry is just as important. Especially making connections with other artists that work with other mediums. Painters, dancers, film makers, audio visual artists, are all people you should be friends with.
Working together with these sort of people can elevate your game to another level. Plus you might be able to qualify for a grant or two. At the very least, working with these people will give you new experiences and hopefully a new product you can share with your fans. Although it may not be hologram Tupac, the product will probably be much cooler and better than anything you could have done by yourself.
