I've finally listened through this, and it's quite interesting. Predictably, Hampson is best in the songs about soldiering. It's rather bizarre and monotonous to put "Revelge", "Tambourgs Sell", and all of the other songs about soldiering, together in one big lump. It's also rather lame to end with a rather perfunctory performance of "Urlicht". But some songs do gain from the more "chamber" orchestra treatment (one each in the strings, except for two violins), such as "wo die schoenen Trumpeten blasen", and "das himmlische leben" (the original version of what eventual becomes the finale to M4). In no way would I recommend this over a solid "traditional" version, such as Szell, Bernstein, MacKerras, Chailly, Stenz, or Boulez (the Abbado is a complete snooze). But this would make a decent supplement to those. I like that Chailly uses a tenor in "Revelge" - that kind of makes the marching soldier more of a wind-up toy, and less a front-line warrior.
