I am surprised, given the quality of sound on this recording, 
                  that Opera d’Oro has seen fit to re-issue it under their 
                  “Grand Tier” de luxe label. It has long been available 
                  in their standard series but has drawn some justifiably acerbic 
                  comments regarding the muddiness and inconsistency of sound, 
                  with virtually no higher frequencies and ensembles dissolving 
                  into mush. Individual voices fare better but this still sounds 
                  more like a poor amateur recording than the usual acceptable 
                  mono radio broadcast. Most of Act 3 is horribly muffled. 
                    
                  Furthermore, only four years later Karajan made an excellent 
                  studio recording of this opera for Decca with many of the same 
                  cast, using the fuller, later, 1908 revision by Rimsky-Korsakov; 
                  here Karajan streamlines the opera, using mostly Rimsky-Korsakov’s 
                  first version from 1896 but also making some large cuts, including 
                  Pimen’s first narrative and he rather perversely swaps 
                  the order of certain scenes, so that the scene in Pimen’s 
                  cell precedes the Novodievichy Square scene and the last two 
                  scenes are reversed, such that Kromy Forest precedes the death 
                  of Boris. This might be said to conclude the opera more dramatically 
                  but it also undermines Mussorgsky’s intention to switch 
                  the audience’s attention back to people, who in themselves 
                  constitute a major character in this opera. It also subverts 
                  the pathos of giving the last word to the Simpleton. I am thus 
                  mystified as to why anyone would see this live performance as 
                  more desirable than the 1970 studio recording, given the cuts, 
                  tinkering and its gross sonic inferiority. 
                    
                  A case might, however, be made for the enhanced drama of a live 
                  occasion and more energy in Karajan’s direction yet tempi 
                  are only marginally slower in the Decca recording and it in 
                  any case provides so much more clarity and detail that the comparison 
                  becomes otiose. Another claim is that Nicolai Ghiaurov is fresher 
                  and more animated live in 1966. I hear little difference; we 
                  are talking about only four years when he was still in his absolute 
                  prime, singing perhaps his greatest role under a conductor who 
                  rarely revised his approach to a score once he had worked it 
                  out to his satisfaction. Again, a preference could be expressed 
                  for the darker-voiced Marina of Sena Jurinac over that of a 
                  slightly squally Vishnevskaya but both are excellent. Anton 
                  Diakov’s Varlaam is a distinct liability in 1966: he is 
                  harried by Karajan’s excessive briskness in his narration 
                  about Ivan the Terrible in the town of Kazan and bawls his way 
                  through it horribly sharp; things go better with him at a less 
                  hectic pace in the studio recording. Otherwise, apart from where 
                  the roles are taken by the same singers, the differences amount 
                  to a game of swings and roundabouts: both Finnish basses Kim 
                  Borg and Martti Talvela (himself a notable Boris) are imposing 
                  as Pimen, Zoltán Kéléman reprises his oily, 
                  menacing Rangoni, and a slightly effortful but heroic Ludovic 
                  Spiess marks an improvement on Alexei Maslennikov, who was promoted 
                  to Grigori by Karajan in Salzburg but is happier reverting to 
                  the Simpleton for Decca. 
                    
                  Oddly, Opera d’Oro does not provide the full cast list 
                  so I have supplemented it above by recourse to another source. 
                  Although having a libretto is not so much welcome as vital to 
                  Anglophones, it is odd that they insert photographs of a clearly 
                  much older Ghiaurov (as King Philip?) and another of Borg whereby 
                  both are clearly costumed for other roles in other operas. I 
                  do not see a strong case for preferring this live Salzburg version 
                  over the later studio recording. Although Karajan’s “diamond 
                  and sables” approach to the score has been criticised 
                  as too opulent, for me, he and Ghiaurov still manage to bring 
                  out the searing drama of this epic opera in both versions. The 
                  difference is that in 1970 you can hear it properly.
