This tune was written during rehearsals for the already half mammoth opus Mirror Future. I think I was focussing on including Heritage into it when this came about for sense of urgency ~ and Mystified happened about a week later, in much the same way ....... ;o)

For later perfection, on guitar, I'm thinkin more of an Oysterhead meets Tool sound for the main riffs, like an open E nut chord for punch (maybe even Em) but then definitely classic Yes vocals pretty much following the bass melody presented here. Structure wise, it goes around the classical based riffs, thru blues, n back to where it started from ~ full circle ....... =oP

See also the groovy pseudo virtual album (strangely enough) entitled Mirror Future for other groovy jams from the same similar Shadows era ....... ;o)
