For a 200th upload (10 times less than David !) let's go good old - and somewhat bombastic - French symphonic music :-)
Guilmant First sonata was first written as a symphony for organ and orchestra. That explains the 3 parts chords at the pedal near the end of the final, to compensate the absence of an orchestra ; the organ part with orchestra has only usual octaves at the same bars.
This Final is a kind of a toccata, alternating with a choral-like theme (like in Dubois' or La Tombelle' toccatas of the same period).
I took a tempo probably too fast for my fingers, but I "see" this piece as primarily stormy rather than majestic. But, if you want, you can find professional quality versions previously uploaded, for instance
