Get this CD! You are unlikely to find a public performance of Bruckner's "00", and there are not many recordings either. It is lovely music, and very interesting if you know the later Bruckner symphonies. That Tintner, Royal Scottish National Orchestra, and Naxos, can produce a good recording goes without saying.
Symphony "00" is an exercise during Bruckner's studies. It is clearly not mature Bruckner. Tintner, in the acompanying booklet, compares it to Schumann and Mendelsohn. As a Scandinavian, I am even reminded of Grieg sometimes (his symphony, also an early work, is contemporary with Bruckners "00"), but he was also influenced by Mendelsohn, so Tintner is, of course, right. Then, in the middle of it all, you can hear the coming Bruckner (ending of first movement, scherzo). The juxtaposition of Mendelsohn and Bruckner, and the glimpse of Bruckner's development as a composer, is fascinating! It seems that he went through both a Mendelsohn period and a Wagner period, with more and more of himself, before he became the "real" Bruckner - nobody else could have written his 9th!
