Source: the Mondo Musica booklet and back card in incoming/Rimski-Korsakov - Sadko, Karabtchevsky/scans (MFON 22248, barcode 4026727222484), which print "Live Recording - Venezia, 3-2-2000" (Italian d-m-y); independently confirmed by operadis http://www.operadis-opera-discography.org.uk/CLRISADK.HTM, whose entry for this set reads "Recording of a performance in the Palafenice, Venice (3 February 2000; see OPERA May 2000 pp.580-583)".

Top billing corrected: the title role was not among the three noted. The Mondo Musica booklet cast page (MFON 22248, scans/scannen0002.jpg and 0003.jpg in this rip) lists the cast in the order Sadko - Viktor Lutziuk, Volchova - Dagmar Schellenberger, Il Mare Oceano (Sea King) - Vladimir Vaneev; the Venetian Guest is one of the three brief merchant songs. Same cast order in operadis http://www.operadis-opera-discography.org.uk/CLRISADK.HTM
