Bach Prelude and Fugue in C minor BWV 546 

The Prelude here is one of Bach's most imposing, and was composed some significant time after the five-voice fugue, though one can only speculate at reasons for the disparity in time.  Perhaps the maestro needed a work at short notice, so revived a previous work, adding a new first part.

Vierne Symphony No. 1 in D Minor, Op. 14 for Organ: Final  

The first of six symphonies, No 1 was composed between 1898 and 1899, while Vierne was serving as assistant organist to Widor at the Church of Saint Sulpice in Paris. Vierne was considered one of the greatest musical improvisers of his generation and his music was perhaps the most idiomatic for his chosen instrument inspiring most of the great Parisian organist-composers who followed him.
