I also voted 9, which is reflecting that it's a 10 for the mix and fidelity and an 8 for the album itself.
The Big Express is one of the two "lost" XTC albums sandwiched between the touring years of the band and the breakthrough of Skylarking (and even The Dukes of Stratosphear). Opinions are divided on those two albums. Mummer appears to be a love-it-or-hate-it type album, some people find it lackluster whereas I adore it and think it's where XTC are exploding into technicolor after some more monochrome (although excellent) albums. It's not without its faults, but it works for me just the way it is.
The Big Express was one I had much more difficulty getting into, and it's even easier to understand why when I hear this new eye-and-ear-opening remix. The production choices made for a very fatiguing listen, and the 2001 CD remaster that was my only previous experience with the album did it no favors with its awful remastering. I've only listened to the 5.1 mix, but it opens it up and makes much more sense - I always wondered where did Dave Gregory go on this album, but in the new remix there is suddenly guitar interplay again, there are melodic guitar flourishes that were buried, and the industrial clang of the drums is not as oppressive anymore.
It's still not the best XTC album - a few songs, particularly on side 2, are not at their top level, and it still falls victim to their stubborn will to be quirky, different and clever (Andy Partridge, I'm looking at you). I love The Tony Williams Lifetime's "Emergency!" album as much as Andy Partridge, but it wasn't a good idea to try to shoehorn some McLaughlin lines into the opening of "I Remember the Sun" for instance. Actually, that could be Dave Gregory, but the style sounds more like Partridge.
It's trying to fit a bit too much into the songs and album all at once, so it is still a slightly claustrophobic listen (they would even top this approach on Oranges & Lemons), but the good things are even easier to appreciate now, and there are some wonderful gems here. "Wake Up" and "Train Running Low on Soul Coal" are two of the high points both musically and mix-wise. "Seagulls Screaming Kiss Her Kiss Her" was always great and one of Partridge's best lyrical moments, and I've always had a soft spot for "This World Over" even though the accusations of a Police-out are true. "Shake You Donkey Up" really comes alive in the 5.1 mix. I feel the first album side is stronger than the second, which is more pleasant but also more forgettable bar the stunning closer. All in all, I used to rate this album a 7.5 musically, but I think it's close to an 8 now with this new mix.
Can we get English Settlement and Mummer now, please?
