Excellent word, though it generally has negative connotations. I briefly thought "coruscating", but that's probably far too positive (although one definition is "scathing").

I dig the album, but it's extremely free and the alto (in places) brings to mind performers such as Akira Sakata. 😉
It also includes the under-recorded (IMO) bassist Jean-François "J.F." Jenny-Clark.
