How hard is Apocalypse in 9/8 from Supper's Ready

Could you post a video playing it?  

I don't think the Supper's Ready organ solo is as difficult to play as the piano intro to "Firth of Fifth," but then again, I am but a humble prog bassist.  All of those black & white keys confuse me.  

Congrats for your achievement... It may be good news for anyone who might look for keyboardist playing a similarly built solo ! 

If your ambition is to play more complex parts you'll just go for it and, given your high motivation, we can only look forward.

The most complex possible parts are very long with many interwoven lines, patterns that won't repeat, demanding very quick and precise moves, crazy polyrythms and harmonies etc, so that Apocalypse solo has a lot of ingredients, but is still quite far from that top. If you choose a superbly sounding part that only lifelong trained extremely talented World -class players can master at their very top, you'll get the ultimate legend aura, but since it's possible to impress or get the total trip with much less sacrifices, only people who can't help it taking extreme lifelong challenges will go for it. Time will tell !!

No big name possible without a lot of touring, or sort of being a lottery winner. There are countless players one could admire for their talents... But if one just enjoys playing others' parts, no shame for being proud, really !!!

I have friends with similar music taste as me, but actually jamming on odd time signatures or playing those long prog songs is something that I still wish to do
