I think what Nickel Creek is saying is that the audience does not know the band members as real people, the audience only knows Nickel Creek as band members. "All they get out of you is what they get out of the show." The "beauty and the mess" is both the good and the bad in the lives of the members of Nickel Creek. The audience doesn't know them personally so the audience cannot share their pain or joy. I think the phrases "blue water" and "pulling myself under" refers to an ocean. This ocean symbolizes the "oceans of people" in the world. Nickel Creek tries to hide their own personal lives as they hide back into the sea of people. Nickel Creek is fascinated because in the "spotlight" in front of an audience the band members can choose to be whoever they want. Nickel Creek also feels that their emotion comes through not only in their words but in their music which is also just as powerful.
