I have been looking for recordings of Harry Bertoia's works for some time without any luck. There are some available on vinyl, but that was not what I was looking for. I recently discovered this box set on importantrecords.com. I ordered it even though it was out of my usual price range and received it this week. It is an 11 cd box set with a nice booklet included. His recordings made with his handmade metal instruments in his barn in rural Pennsylvania are incredible. I've spent a lot of time listening this week and am amazed at the sounds he produces. I thought I would get bored with this many recordings of seemingly the same thing. Each piece taken from his original tapes is a journey worth taking IMO. I can only imagine what this would sound like live in his barn. The set is kind of expensive at just under $100, but I'm not regretting the purchase. There is also a digital download available in wav or mp3 for about $50 with a pdf of the booklet. I hope to be able to make the journey to his place in Pennsylvania sometime to see and hear his creations in person. If you are not familiar with his work I would recommend going to the Important Records site where they have a mix available or search youtube for examples.
