I just saw Symphony X with Sonata Arctica the other night in Phoenix. I've been a fan of SA for a long time and it was so great to see them live after all these years. I've never seen them tour the US.
Symphony X was awesome, as expected. Personally I'd have loved to hear more from them off their Divine Wings or Twilight on OIympus albums, but that's probably just me because those two albums specifically take me back to a pivotal time in my life.
