well apart from the guitar of course, but my pal is a guitarist so we have that covered

well, you are limited to 4 voices…definitely more than that going on in that video
add an Octatrack to the mix and you could sample/mangle (even the guitar) 
Also would want to have a box full of Serge Modular units/Euro Rack for the A4 to control to get remotely close.
Tangerine Dream’s Klaus Schulze Rheingold has been using 7 Polymorphs and 7 Rave-O-lution 309’s live for many years now and then there’s the dozen synths. Layers are the name of the game here, like tapestries of sound.

But if I had some vintage synths and a eurorack I feasibly could?
Perhaps re-watching that video, the whole thing, will tell you there’s a LOT more going on than one box will give you. Look-up the referenced electronic musician in my prior post and see exactly why he has 7 Quasimidi Polymorphs, and 7 Quasimidi Rave O Lutions…plus a load of other instruments. The A4 is surely a beast, but would surely need all the other Elektron Boxes to even get close.

I just do this for fun and I find myself running out of room with 4 voice A4, 8 midi track OT and 8 audio track OT
You can make some great tracks with the A4 alone or even the OT alone. But a big painting is going take a lot of paint and a big canvas.
