Query: disappointing conducting

Karajan has never been a verdian conductor except Otello perhaps. Here his tempi are so slow that Verdi looks a slow waltz. The singers save the day, Freni is great and so, and maybe more, is Cappuccilli. Very elegant Van Dam as always. Great King Ghiaurov, vocally out of place Raimondi, his voice has no weight to carry the role of the Inquisitor. Carreras has still something left of his unbelievably beautiful voice he squandered irresponsibly in few years,after a more than promising start, Baltsa is less vulgar than in other occasions and she is the weak link here together with Raimondi. Uneven rendition, but Don Carlos is a hugely complex undertaking so all considered 4 stars for the effort of the singers.
