I too admire Honegger's music, especially the 2nd, 3rd and 5th symphonies. I treasure the famous Karajan version of Nos. 2 and 3(which I believe is still hard to beat!) but I also have versions of No.3 "Liturgique" conducted by Michel Plasson, Mario Klemens, Paul Sacher and Takuo Yuasa-all acquired because I was seeking other works by Honegger on the respective discs!
"Jeanne d'Arc" has been mentioned. I would also like to draw attention to Honegger's other interesting choral works like "Le Roi David",
"Cris du Monde", "Les danse du mort" and the beautiful Christmas Cantata. All of these are worth hearing! Try the Mime Symphony "Horace Victorieux" as well!
