Ok - so to clarify first off that all of the DVDA tracks are present in the movie 5.1 sound track with the same mix and placement. This being the film there is of course more dialogue and FX mixed in but the music gets prominence in the mix and if anything it kicks harder here than the DVDA. The DTS HD Master Audio is 24/48 but is transparent in perceived quality to the DVDA. It's noticeably lifted in the highs with a more rewarding crispness to the cymbals and snares. The songs are also truncated where appropriate to onscreen activity with fade outs and ins alongside start-stop breaks.
But the real thrill is that some of the rest of the tracks that were missing from the DVDA are here and they're fully discrete. They are; I'm One, Bell Boy, Zoot Suit and Get Out And Stay Out. These ones at least were found in part through the chapter names, I've yet to highlight any others.
'Bell Boy' is superb with phantom rear centre for the weird backward synth line just after Keith Moon kicks in on the mockney vocals front and centre with the harmonies coming in like a viking monty python chorus from the rears alongside honking synths.
'I'm One' is short but sweet with alternate guitar and pianos in the rears chiming out against their opposite numbers in the fronts with a really pleasant reverb that swells to fill the room. Blink and you'll miss it though.
'Get Out And Stay Out' kicks in from the rears and anchors the pianos and bass behind you with crisp guitars in the front left and percussion spread across the front. Townsend sits a little lower in the mix front centre. I'm watching this as they intended but it's clear from the mix that you do indeed need to turn it up and you can and I did. A lot.
'Zoot Suit' begins all around you in plaintive style, all shimmering cymbals and swells elegantly until the angry growl of Moon's drums falling down yet another endless stairwell cascades through the front as pin sharp keyboards and pianos ring out with real urgency from all corners.
More punch without distortion as you crank the volume really supports the spectacular job they've done to the movie itself, this sonic upgrade actually works in harmony with the picture - the rear sound field constantly in use either defining space through judicious reverb or full blown directional fx describing action seen and unseen.
What have we learned? Assuming you have a Bluray player and if you like the film or soundtrack enough to buy the DVDA box set then the additional expense here is negligible to add the film in incredible quality to the music you already have where it rightfully belongs; alongside it's brethren in glorious 5.1. If you don't own the DVDA box set then you're equally cursed and blessed because you get the extra tracks but at the cost of most of them being minorly truncated but it's a small penalty compared to hearing the mighty Who thunder around you over the course of the film. Phil Daniel's anguish is so perfectly rendered in the print - those incredible eyes piercing right through the immense music like amphetamine powered laser beams.
But what about the huge quadraphonic pink elephant on dexedrine in the room? I've no idea if these additional tracks existed before the release of the box set but I'm going to go with after because it makes no sense that if they were finished that they weren't originally included. With the four tracks I've mentioned here it makes 12 tracks in total from the original soundtrack which must make it worthy of a possible BDA release. Maybe even a combined Bluray and BDA release? I'm not aware of the reasons why the DVDA is incomplete and these additional tracks don't render it complete but they are clearly fully mixed session masters and they're sitting in a near line condition somewhere right now and they're just ripe for it.
