The box set sounds cool. I am hardly a jazz expert but am recently becoming more openminded to the style. Must be old age, or the fact that I've pretty much heard all the metal. I figure a good way to get into jazz is through fusion, and bands and artists such as Jeff Beck, Mahavishnu Orchestra, Tommy Bolin and Al Dimeola. Jazz is certainly as diverse a musical world as is metal, lots of different shades.
