This is another great recording from the late 1960s re-released on the Philips Duo label at bargain price, they provide an excellent source of the chamber music of Mozart, Beethoven and Schubert. The string trio has been a much neglected music form, the only ones of note from this period have been the great Divertimento K563 by Mozart, these 5 from the young Beethoven, and one from Schubert. And they are all fine compositions, very well worth a listen. These from a 20 year old Beethoven are lyrical and joyfull. Despite the age of the recording the sound is very acceptable, and the performance from the Grumiaux Trio is superb.
As this recording is about 40 years old it must be expected that there are better performances available, but I would suggest that you don't worry about that, this one is very very good, and very cheap. Without hesitation, 5 stars.
