Hi there,
Between driving up and down the S.F. peninsula and cleaning house, I've been able to work in a Mahler X fest. Although I enjoy listening to all the versions (almost), my opinions come out pretty much as they already have been. By far, my favorites are the Ormandy - now available in pretty good sound - and the Litton/Dallas (Carpenter version). Gielen is great with the more "expressionistic" moments of the work. Hence, his fourth movement (second scherzo) and the faster development section of the fifth movement, are both excellent. But I don't like his almost absurdly loud solo bass drum strokes, and I truly feel that his second and third movements are pretty-darn prosaic. The poor little "Purgatorio" movement, in particular, really gets short changed under his direction. Ormandy is just more consistant throughout, and his Philly string section was just unbeatable in those days.
Carpenter's version is wild and woolly - often times stepping into the even more expressionistic sound world of Alban Berg - but his orchestration and pastiche composing sounds more idiomatic of Mahler - to me, anyway - than Wheeler, Barshai, or Mazzetti do. In fact, weirdly enough, I think it's Barshai who sounds the least like Mahler. I hate to say that because I know he does terrific Shostakovich, and has made a really good recording of the Mahler 5th. But I'm afraid that I just cringe at a lot of the stuff he comes up with. Wheeler isn't so bad overall, but his second movement (first scherzo) is chalk full of really unidiomatic percussion writing for late Mahler, especially with the snare drum and bass drum. It's also strangely light in the lower end of the orchestra: tuba, double basses, contrabassoon, bass clarinet - all of these instruments are greatly underemployed (like me). The Rattle/BPO Mahler 10th (Cooke III) also has terrific string playing, but EMI has sure let him down in terms of sound quality. In some respects, it's actually the worst sounding one in my collection. Rattle's is available in a DVD-A disc, and I'd like to pick that up someday. But truthfully, I'm very happy with the Ormandy. I'm afraid I'm just not a fan of Rattle/Birmingham because, once again, the bass drum is just ridiculously loud (Mahler only wrote forte - which Cooke stuck to - and Cooke adds "muted").
I'd really like to see somebody do a good commercial recording of the Samale/Mazzuca version. In many respects, I think it's the best overall version of any. Like Carpenter, they address many of the bigger picture issues of the work: the end of the first scherzo (second movement); doing something different with the da capo repeat in the "Purgatorio"; making more of the climax in "Purgatorio"; making more of the expressionistic outbursts towards the end of the second scherzo (fourth movement); making the reprise of the first movement's "expressionistic" anti-climax louder and more frightening in the fifth movement; doing something, ANYTHING, with the string dominated, Merchant-Ivory sounding music that happens in the back half of the fifth movement (less prostate and dull) - these are just some of the bigger issues that both Carpenter and S/M address. The others, I'm afraid, just add lots of lots of useless filigree without thoroughly addressing these shortcomings. Samale/Mazzuca, on the other hand, do address these issues but without going so far into the sound world of Alban Berg ("Wozzeck" and "Three Pieces" come to mind). In a sense, S/M's orchestration sounds a bit more like Schoenberg, and less like Berg - sharper and more rhythmically incisive, I suppose.
Anyway, it's been fun, and maybe this will be the year that I finally get around to doing my own sketches. I'm just not looking forward to copying out tons and tons of parts (I can't afford to hire copyists). Much will depend on what kind of work I find, and how much time and energy it takes up. I do need the money! Anybody want to take musical dictation?
