I think the Penguin Guide overrates this a bit, having now upgraded it to their new top rating of 4 stars, ****, and retaining the Rosette. I agree it's a very nice CD but would give it *** Penguin Guide stars and no Rosette. The performances are very good, IMHO, but only the last is really inspired. I have to agree with the PG that the quality of the 1988 recording is very good. I think it is one of the best of the early Naxos recording. Though I detect some minor colorations in the strings, this is much less objectionable than with a larger ensemble. But it makes a lovely sound. Here at Amazon, where the usual standards are less stringent, I give it 5 stars.
The Viola Concerto in G is done very nicely. I notice a slight tizzy coloration in Ladislav Kyselak's solo viola and the strings in the orchestra are slightly brighter than they should be, which is true throughout the CD. Still, the recording is well up to normal standards. The performance is relaxed, a little stately as someone suggested, but otherwise I can't fault it.
The Recorder Suite in A Minor comes off quite well, too. Jiri Stivin's playing is very precise and skillful, but lacking in the last bit of panache. But all in all, a very pleasant, enjoyable performance. The Concerto in F for 3 Violins from Tafelmusik is also quite well done.
The Concerto for Two Horns, also from Tafelmusik, is superb. The two brothers, Zdenek and Bedrich Tylsar, play with great style, and seem to inspire everyone else, too. This performance is full of fun. It really is pretty special, and I would give it a Rosette.
As I said, the recording is quite good. I can cure the slight tizziness in the highs using by turning the Tilt control on my Quad preamplifier down 1 dB. I suspect a little cut with a normal treble control would work, too. But this is nitpicking, as the sound quality is really quite good as is.
