I have the Gunter Wand Bruckner DVDs Symphonies 4 to 9 (except #7 I have on a LP the Koln version).
The recorded sound from this series is very detailed and makes it easy to hear the solos by the oboes, clarinets, etc. The sound is especially clear when recorded in the concert hall vs. the cathedral. Bruckner's music goes from loud thundering heaven storming horn dominated climaxes to low, sometimes very hard to hear sections. These DVDs do a great job at capturing the lows so that the audio is very detailed, audible, and enjoyable. The playing and conducting is excellent. The horns are very important with Bruckner's symphonies and the better the horn section, usually the better the performance. The horn section in this orchestra is very good, though maybe a rung or two lower than Barenboim & the Chicago Symphony Bruckner cycle from 1973 to 1981.
Overall, this DVD series is a treat to both watch and hear and Wand is a true master with Bruckner's symphonies
