These guys are one of the best new prog rock bands out there. I believe the band is members of the Flower Kings and Van Der Graaf Generator that came together with a new singer. I have "A Place in the Queue" and "Not As Good As the Book" and love both of them. A Place in the Queue is actually my favorite album right now along with new Opeth.
