Query: A Valuable Item to Collect

This is an extremely valuable recording for anyone interested in the different schools of violin playing in the early 20th century. So many violinists are represented and it is awe-inspiring to realise you are listening to the great masters! The program notes by Tully Potter are very detailed and they make very interesting and informative reading, with equal dedication to each violinist (some smaller names are included with the bigger ones). On the down side, there are problems with some of the noisiness of the actual recording, but that is to be expected with such old material. I think some of the performances don't carry well in the recording process - seeing these people perform would have been very different. Nevertheless it makes for thought-provoking on how performance practices and styles have changed in such a short amount of time. I thoroughly recommend this historical document.
