Yes, the Bertoia box is a great set. Sonics are terrific. More releases are apparently in store from the Bertoia tape archives. I'm waiting on an LP of previously unreleased pieces that was part of the Bertoia archive Kickstarter campaign that should be available in the next few months. The LP set is great, too (especially the covers), but the pressings are a bit iffy, as I think they date back to the late 70s.
