I had the fortune to be introduced to the music of Wagner when I was 14 years of age, and immediately loved the music, albeit in small doses for a number of years (Overtures, Entry of the Gods into Valhalla, Forest Murmurs, Siegfried's Rhine Journey etc., all without vocals). Gradually, I acclimatised to hearing some singing, although I at first felt that it spoiled the sound !
After hearing some of the Decca/Solti Siegfried, I bought it complete on LP, and subsequently have purchased the Bayreuth/Boulez and Solti complete 'Rings' on CD, and also now DVD versions by Chereau/Boulez, Kupfer/Barenboim,Pierre Audi/Haenchen, and Mehta/La Fuera dels Baus, and so have gradually got to grips with the detail of this multi-layered masterpiece. Also,having read over 25 books on Wagner, I do feel that a deeper understanding of The Ring's extraordinary power and magic is at last being attained, but never have I encountered such a detailed and enjoyable sound and vision exposition of the work as on these DVDs. Not only do I have a clearer understanding of the 'storyline', explained as it is by Elke Heidenreich, but have a greater understanding of the political and metaphysical aspects, and, also, (and most importantly), a greater understanding of the music itself, thanks to Christian Thielemann's verbal insights and impassioned conducting, and Stefan Mickisch's revelatory comments and piano expositions of the many leitmotifs in this vast work. So much that I have intuitively gleaned over the years has now been articulated and expressed with such clarity that I am beginning to understand it all at last (I think!). I thank the previous reviewer for prompting me to buy this DVD, as I feel that that learning from it has never been more enjoyable !
