Some "French"recommendations:
Tournemire: l'orgue mystique
a cycle of meditations on gregorian themes coloured with late romanticism,
very innovative in form (not unlike Messiaen's juxtaposition techniques)
Vierne: pieces de Fantaisie
Very powerful and highly imaginative music. Look out for "Der Rhein".
(Another excellent recording available by Ben van Oosten; glad you liked
the symphonies).
Langlais: Meditations sur l'Apocalyps
The perfect syllabus of French 20th century organ tradition.
Franck: Chorales
Numorous fine recordings available.
