Others, elsewhere, have recently paid £60+ for scarcely any more than has been brought out in this set, for a fifth of the price. They mostly seem unimpressed. However, for sensible money, this 3 disc set (ignore Amazon saying it is 2) is a bit of fun, and good value.
It's clearly a cut down assemblage of the expensive four disc package, 'cos the 5.1 surround sound DVD is actually labelled "Disc 4". Disc 2 contains stock copies of the original 1973 album. You probably won't have bought this set for these. It's the 2009 "remix", and the 5.1 surround sound tracks on the DVD that you'll have been after.
I chased up a copy of a surround sound version of the original album allegedly issued a few years ago, eventually baulking at the price (£90 or more from some dealers). I'm therefore pleased that something has become available at a far more accessible price.
And I like it. As remixes go, it's fairly subtle - instruments brought further up in the mix at key points, and things like that. On my system (not expensive by any means), it is generally crisp, with masses of small detail even the most avid fan won't really have heard before. Oldfield has exercised a very light remixer's touch, and while one could quibble endlessly about whether this instrument or that one should have had more, or less, prominence at any given point, it's down to the artist at the end of the day.
Speaker separation, all important to the surround sound fan, is very good. The very deep organ notes come at you through your feet, too!
The Viv Stanshall Sailor's Hornpipe is an indulgent piece of fun, and it's good to have a decent copy of the 1973 BBC2 "live broadcast", but for me, these are embellishments to now having a decent 5.1 version of one of the best albums ever.
