These performances date from the early 1970s (if I remember correctly), so I, for one, am willing to overlook the inevitable background hiss from the master tapes. As for the quality of the re-mastering, the hiss could have been reduced further, but only at the expense of the purity of the recorded music - you never get something for nothing in this life. Jack Brymer's clarinet tone had a liquid, velvety quality like nobody else's I've ever heard and for me it is more important to preserve that in this recording than to reduce the tape hiss. Brymer was one of the finest clarinetists of the 20th century and his performance of these works is characterised by a calm maturity that I find absolutely spellbinding. These are legendary performances by a legendary clarinetist. BUY THIS CD.
