Hmm...favorite band. Well Symphony X undoubtedly always will be with what they can achieve in soundscapes. But as of late, the last two albums and especially THIS one, I feel like I'm watching Jeff Goldblum talking about "Insect Politics" in The Fly. And I really fear for the future with this band since they've joined this new label and started catering to younger/newer fans by emphasizing the heaviness factor, while neglecting the progressive and the melodic side that made them such a musical force to begin with.
Right now, the band I am the most positive about is Subsignal. Their second opus proves that this band is growing and improving. And while not quite as staggering as the preceding and sadly split-up Sieges Even material, they're recording some of the best progressive music out there right now that is way better than anything that most are offering.
Fates Warning, another favorite, I'm just going to put a <?> besides since they'll be without Mark Zonder. We'll have to wait and see.
Magenta is another favorite from the last decade as was Moon Of Steel.
Historically, for me, Rush, Iron Maiden, Black Sabbath, Genesis, Camel, Pat Benatar, Led Zeppelin, Marillion(Fish-era), (80's)Metallica, Megadeth, Heart, Billy Joel, Blondie, Ozzy, Bruce Dickinson, and Saraya were and are really huge in my musical heritage and cornerstones for my further explorations into the magical world of prog.
