Simon Rattle has recorded a lot of 19th century music and most of the results have been dismal. There is little to recommend by Rattle in pre-20th century repertoire. A few Haydn symphonies, some pretty good Brahms, bits of Mahler, Ein Heldenleben by Strauss which is just at the cusp of the 20th century. Alright, so Rattle is not the conductor to go to for the great classics. However, when he records modern music, he seems fully in tune with it's sound and style, plus he has less competition on the market to boot.
Alban Berg wrote twice for string quartet, and both results stand tall in his output. On this Naive disc, a reissue of an earlier Montaigne release, the Arditti Quartet perform these pieces. The lineup of the Ardittis at this time was Irvine Arditti and David Alberman (violin), Levine Andrade (viola) and Rohan de Saram (cello).
If you don't already have any recordings of Beethoven's late string quartets, by all means get this one by the Alban Berg Quartet. There hasn't been a set to equal it since it was originally released in a different configuration in the early '90s - the Emerson's overly enthusiastic but not especially insightful set? oh, come on! - and there hadn't been many to equal it before the '90s, only the Quartetto Italiano's wonderfully balanced and incredibly lovely set, the Quatuor Végh's supremely intense and transcendentally sublime set, and the Berg's own earlier, extremely concentrated and austerely passionate studio set.
