One of my musical guilty pleasures! Hardly serious, unless one means serious fun. The musical skill is top shelf. As well, this Ol Drake LP will likely appeal to progressive or technical death aficionados. There is a distinct classical influence throughout these instrumental songs, not just on the nod to Bach. Yet this is not serious thinking man's progressive / death metal & it doesn't claim to be. I think of this much as I do about Cannibal Corpse; great fun but only serious in its fun.
Favorite track: I'll Be Bach (Get It?).
