This set of legendary performances by LaSalle Quartet of all string quartets by Schoenberg, Webern, and Berg has been reissued by Brilliant Classics Schoenberg; Berg; Webern - String Quartets at a very attractive price. Buy it now before it disappears again.
The performance here is outstanding, with well judged tempos and very tight ensemble. The sound is very polished, which is well captured in the CD transfer. There are only a few things I'd like to point out.
1. The first violin seems to have wider vibrato than commonly used these days.
2. The breathing is sometimes audible.
3. The soprano Margaret Price, with very wide vibrato, does not seem to have the right timber for Schoenberg's quartet in f sharp minor Op.10. (Yes, there is a soprano in the "string quartet"!)
4. If you have Alban Berg Collection, you already have 1 of the 4 discs.
However, these small quibbles need not deter you from buying this outstanding set at the current Brilliant Classics price. And by the way, if you like historic performances, the set In Honor of Rudolf Kolisch, which has almost all pieces performed here, is not to be missed. Kolisch Quartet premiered many of the pieces in the set, including Schoenberg's last 2 quartets, Webern's Op.28, Berg's Lyric Suite (and Bartok's 5th).
Most highly recommended.
