I thought I'd throw in a recommendation for Maurizio Pollini's new DG disc of KV. 414 and 491 (nos. 12 and 24 - I guess Pollini has a thing for integers congruent modulo 2, but bad math humor can wait for another thread). In keeping with an earlier disc, Pollini himself directs from the piano. I'm not sure if that's a universally great thing, since some conductors are very responsive to and intelligent about the soloist (e.g., Boulez' 1974 recording of KV. 537 with Curzon and the BBCSO, out on BBC Legends); in this case, however, I would say that Pollini does a reasonable job leading the Wiener Philharmoniker.
This material is, of course, part of the central repertoire for the WP (broadly speaking), and one reviewer raised the question of how much is Pollini and how much is the native style of the WP. I'm not prepared to answer that, leaving it for wiser heads, though I have my suspicions. In any event, there is a good sense of balance between soloist and tutti. The sound is pretty good, though the packaging makes it clear that these were culled from concerts. Pollini's performances are really quite nice, too: his tendencies toward balance and precision really suit the music here nicely.
Granted, it's big-band Mozart, but it's never bloated. This disc is, also, another entry in a string of reasonably intelligent major-label releases (Aimard's Bach, Hahn's Schoenberg and Sibelius, i.a.). It's probably more of a testament to the individual artists than the labels, but it's nice to do without another so-so recording of a warhorse most listeners could reproduce blindfolded.
