For those who like the recording of the Liturgy in znamenny chant by Grindenko, I would recommend "Early Russian Ecclesiastical Hymns" by the Moscow Patriarchate Choir, which was released on the "Russian CD" label as RCD 15001.
It's available from [url=http://www.liturgica.com/cart/musicInfo.jsp?catNo=AJ070]Liturgica[/url] and [url=http://www.musicarussica.com/discdet.lasso?-database=musrus_cds&-response=discdet.lasso&-layout=CD_detail&-RecID=34437&-search]Music Russica[/url].
The interpretation of the znamenny chants by director Nosov (later Hieromonk Amvrosiy) is less "modern-sounding" (to my ears, at least) than Grindenko's-- I happen to somewhat prefer it, others' opinions may vary. The singing is peaceful and prayerful, not concert-hall style.
Hope this is a welcome find for someone.
