For a very long time, I couldn't get Maazel's way with Mahler or, for that matter, anything else he recorded--except a Prokofiev ballet. I found his highly interventionist approach almost unbearably self-serving. (This from a person who adores Bernstein's Mahler). After listening to his recent live performances with the NYP, I had a big change of heart. I found his interpretations full of passion, impeccably played (the NYP is remarkable, and the finest orchestra in the world when they wish to play at their best), and infinitely preferable to the recent spate of bloodless, colorless recordings from Zinman, Jansons, Macal, and Fischer (yes, his 4th is quite good but the 2nd and 6th have to rank among the biggest bores in the catalog), and the like. Heavens, De Waart, Boulez, and Gielen are boiling cauldrons of emotion compared to this latter crowd! (I must politely disagree with some of the enthusiasm on these forums with the present state of Mahler interpretations but, for me, it's been a desert in search of water.)
In returning to the VPO/Maazel, I found that my objections were mostly to the atrocious sound (ear-splitting trumpets, in particular) that the set features. However, the interpretations have a lot to commend them: Perhaps the most angst-ridden 6th symphony in the catalog, a 3rd that swings between the widest interpretative extremes possible, a 5th that is terrifying and tormented, a 7th that is almost hallucinogenic, and a 9th that is sublime in the outer movements yet macabre in the internal ones. Also, the VPO is an extraordinary band.
Maazel has been a great whipping boy since he followed Szell in Cleveland. Somehow, we Americans couldn't deal with such a young snot (relative to Mr. Szell's age) following a legend. Also, that Maazel happened to be "American" didn't sit well with many in the music business. In truth, I find Maazel's Cleveland recordings to be warmer and kinder than Mr. Szell's icy perfectionism in most of the repertoire he left behind. Listening to Maazel's recordings in Cleveland reveals that the performances were also brilliantly and sensitively performed. A fact that few bothered to point out or ignore as the Maazel-bashing gathered steam in the press and local quarters. Although Szell's Mahler 6th has attracted a great deal of attention and won many plaudits--I don't get it, sorry--Maazel's VPO and NYP recordings of same reveal Mahler's bipolar spirit better. I am aware that Mr. Szell remains a holy cow for many still and I have enormous respect for his legacy, but I have difficulty in finding any of his recordings to be my "most preferred" interpretation of a given work. My favorite Szell remain the Strauss songs album with Elisabeth Schwarzkopf. (He couldn't get his way with that one as he did in, for instance, the giddy-up and galop Beethoven Piano Concertos with Fleisher and Gilels, or the "please find if Mr. Oistrakh is in the building" recording of the Brahms Violin Concerto.)
I don't like everything Mr. Maazel has done--the Sibelius cycle in Pittsburgh (unfocused and dull), Strauss with the Bavarians (boring)--but I do encourage those who have dismissed him outright to re-listen to his Mahler. I also wish that someone would remaster the Vienna cycle as the sound is simply unacceptable. For those who may not be familiar with the Maazel/Cleveland recording (Decca) of the complete Prokofiev "Romeo & Juliet": this one ranks among the very best sounding recordings ever made as well as being a great performance of the work. A pity Decca didn't record the Mahler/VPO cycle. Chailly's cycle benefits enormously from the sonically-superior recordings even though the interpretations (maybe the 3rd Symphony is an exception) sound superficial and under-experienced--the participation of the magnificent RCO, notwithstanding.
