Planet of Sound is a blog about popular music and speculative fiction. These two things have very little to do with each other.
The main connection here is that I enjoy them both a lot, and it brings me an unreasonable amount of glee to hear SF rolled up in my rock. Even after Star Wars, Lord of the Rings, and Harry Potter, speculative fiction still has the underdog’s air about it. It’s a blast to see rock stars geeking out a little.
In other words, music * speculative fiction = geekery squared.
