Does anyone know of any good instrumental songs that have a progressive feel to them?

With the odd time signature here and there I would prefer.
ESP LTD M-100FM Tone Zone (B)/Breed Neck (N) w/ Coil Splits
Fender Electro-Acoustic
Line6 Studio UX2
BOSS DD-6 Digital Delay/DS-1 Distortion Robert Keeley ULTRA Mod
Electro Harmonix Holy Grail Reverb
Dunlop SW-95 Crybaby Slash Wah
Any Liquid Tension Experiment, like Acid Rain, Universal Mind or Paradigm Shift. Some Dt as well, Ytse Jam, Erotomania, Instrumedly (of course). And the mother of all complex time signature, The Dance Of Eternity.
Stream of Consciousness - Dream Theater

Hell's Kitchen - DT

Presence of enemies Part 1
