I don't see a problem with revised works until debates emerged about Bruckner's various versions of each symphony (I think with exception of Symphony no 7). Tchaikovsky, Mahler and considerable number of symphonists particularly revised their works thoroughly, but it is Bruckner who gets most attention because usually his revision are done under pressure from many who didn't understand him as quoted from one of his admirers "He is a genius without talent".
This symphony is fascinating mainly because the market only practically has original Haas 1890 version and Nowak recordings in the market and only Inbal, as I understand, recorded this 1887 version. What struck me was this symphony's difference from Haas version is like stepping into an alternate universe. It doesn't sound independent from Haas version, yet there is many intriguing differences.
I personally love the first and second movement. The first movement is much more spiritual and mysterious compared to Haas version, whereas the latter sounds rushed when you hear both versions of the same movement. The second movement has much more vigour whereas the Haas version is more simplified and rather, dignified compared to a much more brash 1887 version. My only complaint is the 1887 version of Adagio, with painful counterpoints and very, very sappy climax. No fault of Tintner for that is why the Adagio is the only redeeming feature of 1890 Haas Version.
Georg Tintner maybe the sole sparkling gem of Naxos' compared to a huge array of maestros on other labels like Deutche Gramophon or EMI. Listeners don't simply buy his Bruckner because simply the recording is much more affordable. The Ireland Symphony is on a class on it's own with Tintner leading "Die Nullte" symphony, i considered the best symphony of Bruckner after Symphony no 4 and 8. I think it's one of the CDs that all lovers of symphonic music should own.
