How exactly does one classify progressive music? Is it merely the 70's stalwarts such as Genesis and King Crimson and those who seek to carry on their work? Can a jazz fusion band be progressive? Are Radiohead and Primus part of prog? For that matter, is Asia? We will not attempt to try answering those questions. Suffice it to say that if you have an idea of what progressive music is, you will find we have tried to include everything that falls into the various definitions of the genre. You may not agree with their inclusion, but you will understand why we think they ought to be here. For those of you who do not know, explore a bit. If you are open minded about music, and you like to be challenged by what you hear, this is the section for you. Good luck, and happy listening!
