This is a fantastic release. It has a very unique vibe to it, probably due to it being recorded during the wee hours of the morning (it is said that the multiple sets started at 2 am). The two vocal numbers featuring Joe Williams are fantastic as usual with 5 O'Clock in the Morning being a highlight. The music throughout this LP goes from low key and groovy to blasting, swinging horns and percussion in a single song, almost like the band is trying to wake up the audience and get them out on the dance floor... Over the years, this has become one of my favorite Basie LPs... highly recommended. Great stuff here.
