Tough... well, here's five I could come up with, in no particular order...
Rush - "La Villa Strangiato"
The Flower Kings - "Stardust We Are"
Dream Theater - "Six Degrees Of Inner Turbulence"
Transatlantic - "Stranger In Your Soul", "The Whirlwind"
REALLY hard to narrow it down to five... maybe 5 from each of my top 5 or 10 bands, but never 5, period.
