The book dives into the most important of questions regarding the current state of so called Progressive Rock: Are prog rock bands still progressive or are they rehashing old ideas? The diversity of the modern prog rock scene makes answering the question challenging, but the book approaches from two distinct areas: Progress and Technology. After almost 50 years of influences merging with the genre, does it still resemble the genre that grew in popularity in the early ‘70s? And is that sound worth preserving? The final part of the book asks bands to look forward and imagine where prog rock is going, and if it still needs to push boundaries.
