Query: There is a reason every reviewer gave five stars

There are a few box sets which every fan of music must have. This is one of them. It is too hard to come up with superlatives which adequately describe this set of music. Simply put, this is one of the finest collections of music there is available. Miles Davis put together one of the sweetest sounding groups of jazz musicians ever: with Coltrane, Cannonball Adderley, Philly Joe Jones, Bill Evans, and a few notable others. I think that the era these six discs covers is the zenith of jazz music.Included are the essential cuts which made up "Milesstones"', "Round About Midnight" and other classic music. Whether your tastes run to the be-bop of "budo" or "Two Bass Hits" or the smooth, cool jazz typified by "So What" or "All Blues" (or the whole "Kind of Blue" album for that matter) THIS IS THE PLACE TO BE.Somewhere, someone has created better jazz music. I just have not heard it yet. Until I do, this will more than suffice.
