It moves, both in the sense of changing place, and effecting emotion. A good jazz record, it seems to me, should take you to another place, even if it's only so long as you are listening to the record. In clubs or concert halls, jazz is the music of motion, invention and emotion. Jazz is flexible.
Good jazz contributes to the history and teaches in the modern day.
The above surfeit of hubris in aid of trying to codify my feelings about The Clayton Brothers Siblingity , an album I like very much, but find it hard to get excited about. The brothers, bass-player John and reeds player Jeff, are musicians of the old school. Trumpet player Terell Stafford has been added for this recording. Siblingity is by and large music that would not have sounded out of place at any time during the 50's and early 60's. Though mostly originals, some do include familiar compositions in part, as launching pads for the new work and tributes to their influences.
