Here are some YouTubes of Gretchaninov works that gratified my search for good performances.
- Svete Tihiy (O gladsome light). This April 11, 2011 performance by the Central Washington University Chamber Choir in Ellensburg gave me goosebumps. Their faces reflect the ecstasy I feel listening to them. See how their bodies sway so slightly, leaning into the notes.
- Nunc dimittis (Time to hit the road). Holland Chorale, Hope College, Holland, MI. A larger, older choir with a beautifully balanced sound.
- Vespers. No information about this version, but it is apparently a study compilation that also shows you the sheet music (hope you can read Slavonic). The first piece shows off that great Russian basso sound.
- The cherubic hymn by the Wicker Park Choral Singers of Chicago. Sweet sound, nice balance, solid bass line. Nice-looking room they're in, too.
Meanwhile, check out the State Russian Choir's version of Blagoslovi Dushe Moya Gospoda (Bless the Lord, O my soul).
