Query: late 40's Basie

Some people tend to ignore the late 40's period of the Count basie big band. There's plenty of good music here, although the high energy swing may be lacking in a lot of the tracks. After all, this was the rhythm and blues period, and the Basie band reflected the times. There are some great Jimmy Rushing tracks and some mellow blues instrumentals, but the band still swung like only they could. Any Basie fan won't be disappointed.Just a quick update. The first 5 tracks are from Basies' Benny Moten period and recorded in the early 30's. You can hear the origins of the Basie sound!
