Choral or Classical Vocal Recordings - Must Have


In the last six year I have opened my ears to choral music and classical vocal recordings. I would appreciate hearing what your Must Have list is, so that I can discover more wonderful music that maybe I haven't yet heard.

My list is in random order and is as follows:

-Magnificat by John Rutter - COLCD 114
-Lux Aeterna by Morten Lauridsen, Los Angeles Master Chorale - RCM 19705
-Let Your Voice Be Heard - Cantus - CTS 1201
-Olde English Madrigals and Folk Songs at Ely Catedral, Rutter and the Cambridge Singers - AG500-2
-Vepres by Rachmaninov - The Choral Arts Society of Washington - ERATO 2292-45269-2
-La Belle Epoque, The Songs of Reynaldo Hahn - Susan Graham - Sony SK60168
-O Magnum Mysterium by Morten Lauridsen - Nordic Chamber Choir - BR 100 305 CD
-Requiem by Faure - John Rutter and the Cambridge Singers - COLCD 109

If you want to give your subwoofer a workout, try Telarc SACD-60579 "The Sound of Glory"... Morman Tabernacle Choir. They have the mother of all organs in Salt Lake City.
(This is a Hybrid SACD, but I have no idea how it sounds on a regular CD player).
Jo sumi - the clearest and prettiest soprano I've heard - She is coloratura soprano so higher than regular, and her voice is ideal feminin to me.

The Allegri Miserere is a must but only the King's College Choir version conducted by Stephen Cleobury (c 1984).
Also Richard Strauss' Vier letze Lieder performed by Arleen Auger are transcending.
I agree completely with Gonglee3 about Jo Sumi (in the US, her name is reversed to Sumi Jo, which itself, I guess should be Su-Mi Jo?). Anyway, her voice is remarkable and any of her CDs (which are widely available on Erato) will delight you.
