Andy is a planetary astronomer by day, and also by night since he's an astronomer. Also a founding member of Dr. Lüst, Science Diet, and other bands you likely haven't heard of.
The Gedankenband is a rag-tag crew of veteran eigenmusicians who help Andy turn his music into, well, still music. But maybe different from what he intended. But in a good way. Or something.
