Over the last five years Skepticality has been pleased to interview some of the world's most interesting and noteworthy skeptics and scientists and some of those skeptics and scientists are also gifted artists. This week Swoopy and Derek talk with George Hrab about the release of his new album Trebuchet, which he has been kind enough to provide to our listeners in it's entirety for free as a full album mp3. Among the many topics, and music clips, George talks about marketing this new album via his award nominated Geologic Podcast, and about the subject matter that is, as always relevant to his audience of skeptics and music lovers alike. Additionally Derek chats with New York Times best selling author Scott Sigler, about the release of his book Ancestor (a sci-fi horror thriller steeped in hard science) by Crown books on June 22nd. Scott didn't just stop by to chat, he also has some special give-aways for Skepticality listeners.
