Progressive Metal: Progressive Metal is properly a mix of the progressive art rock of the 70's such as Yes, Rush and King Crimson with the basic sound of melodic Traditional Metal to produce more musically challenging and intricate sounds. The founders and most influential bands in modern Prog Metal would have to be Queensryche and Fates Warning. Both these bands emerged in the early to mid 80s with a definite Traditional style, but distinguished themselves with advanced musicianship and a penchant for elaborate songwriting. Queensryche (or their marketing department) were the first to use the phrase "thinking man's metal" as a selling point, but in fact it was Fates Warning, with their obtuse and elaborate arrangements, that were the more progressive of the two. On their transitional album "Perfect Symmetry" they created a dry, very Rush-influenced sound that was still unmistakably a metal sound, and almost all modern Prog Metal is derived from it in some measure.
But no discussion of Prog can be complete without mention of Dream Theater – without doubt the most influential band in the genre. DT took the basic Fates Warning approach and added layers of keyboards as well as utterly opulent, over the top songwriting that placed a premium on complexity and showy musicianship. Modern Prog Metal was born. Now it is hard to find a Prog album that does not to some degree sound like Dream Theater's defining "Images and Words" album, and equally hard to find a reviewer who can avoid making comparisons. Now that Dream Theater have moved farther and farther away from a metal sound, other bands have moved in to fill the void. And we have bands like Spiral Architect and Power Of Omens who place an even greater emphasis on high-wire musicianship and incredibly technical songwriting. Like jazz and prog rock, Progressive Metal inspires its share of snobbery, and the mantle of "thinking man's metal" has sometimes been used dismissively on the rest of the metal scene. This is a genre that by its very pretensions invites animosity, and probably has as many fervent detractors as fans. Nevertheless it remains a vital and significant genre, not least of which by way of its influence on other genres, for where Prog and Power cross there are some very good bands to be found indeed.
