There is an up and coming Columbia Legacy box set of the Miles Davis Quintet’s tour of Europe in 1960.

This article gives a bit of background to the creative tensions within the band and certainly whets my appetite for this set.

Are there any sax players out there who can enlighten me to multiphonics? If it’s two notes at the same time, does that mean the two combine to create a third sound or is there some technique that means each note is distinct but is played simultaneously. It is clearly easy to do on a piano or a guitar (or any instrument that has seaparate strings), but I can’t understand how two separate notes can sound on a sax (or any other wind instrument), because that is my reading of the comment in the article.
