Please excuse me for coming here in mid-stream; I just noticed this thread. I don't have time to go through all the prior posts so will just beg pardon and write about my utter dissatisfaction with the tempi in HIP interpretations of the B Minor Mass. I am trying to enable my adult children to enjoy the Mass, and send them music files or links on Youtube to do so.
Of my favorite chorus, Cum Sancto Spiritu, there is NOT ONE example anywhere among recent recordings that I can send them. I must go back into the past to find something that does the writing at all justice. I'm not asking for recommendations; I have already found and recorded copies of a few that will serve. I'm just discussing the utter barbarization of musical culture that has taken place among this generation of conductors. The trumpet double triplet at the climax of Cum Sancto Spiritu, so inspired and necessary at that climax, is just a smear in all current day recordings if it can even be distinguished at all in the runaway-locomotive chaos. This defacement alone puts the lie to any tempo decision than an HIP conductor can make. The architecture of the polyphony throughout this movement, a monument to genius, is destroyed like a building razed by Putin. For years I've been looking for a justification of these tempi and never found one. And the tempi in all Bach get faster and faster. This is desecration of art on the highest scale. It is far worse than the Romanticisation of Bach, longer and more languorous tempi, that took place in the 19th and early 20th centuries and is deplored by HIP conductors. Throwing the baby out with bath water, indeed. I am saddened immeasurably by the beauty younger generations have missed in Bach and will never recover.
It's as if a hammer were taken to Michelangelo. (Once again please forgive me for all the detailed discussion of this point I've undoubtedly(?) missed in the prior pages as time doesn't permit me to search thru.)
