Just walked a bit under 3 miles while listening to John Antill's "Corroboree", on the new Naxos CD. I had the volume up to 90%, but rather than turning up unflattering aspects of the performance or shortcomings in the recording, it was just all the more amazing. This is a historically, musicologically important release of an extremely eccentric and almost-forgotten masterwork, in a blazing performance, with some of the best sound engineering I've ever heard. (And when the music calls for huge orchestra, at least a dozen percussion instruments, a truly gigantic dynamic range, and in the finale apotheosis an instrument called a "bull-roarer" which gobbles up most of the sound-space, you need a truly brilliant engineer.)
