Twenty minutes of a riff over which I improvised - and went into a trance while I was recording. 

The moment with the B3 was added later. 

The whole track started as an experiment with Shreddage-2.  I don't think that a keyboard should replace a guitar, but I do think that guitar-like sounds can be used, as they're simply a particular use of synthesis, to create music similar but separate from a guitar.

Instrumentation:
"Heavy" drum kit, Logic Pro
Shreddage II guitar simulator through a Bogner amp simulator
Chapman Stick through a flip-top bass amp simulator
Hammond B3 through vintage Leslie simulator
Steinway Piano
Minimoog Model D (VI)

I Have Been To Another World, And Come Back.

If you like loud pianos, heavy rock and massive drums, you've come to the right place. These are full tracks, tests, works-in-progress, and experiments.  Heavy rock, progressive instrumental, progressive metal, fusion-rock live here. And some ambient-groove for the late-night my-ears-need-a-break moments.
