About 12 years ago, I read a graphic novel about a boy who goes on a spiritual kind of journey of discovery. I can't remember much about it, but in the end, he organizes a rock concert, and the collective energy of the rock concert contacts a space ship, and he and his friends fly away in the space ship. I recall that they're all dressed in white when they board the space ship.
I suspect this was written in the 70's or 80's.
Is anybody familiar with this?
