I was really looking forward to the surround version of "Trilogy". On the whole, the mix is well done, but it is not as consistent as the previous releases: I do not know, for example, why the piano was completely placed on the Rears the title "Trilogy", while from the front speakers. significant noise can be heard. For some downfield passes have not been used for an accurate reproduction. Nevertheless, I speak from a buy rating, because despite the weaknesses makes the album in this variant of fun, although it m. E. is the weakest 5.1 implementation of previously published in this format ELP albums.
