What a revelation!
I had not heard Carolyn Sampson before this recording and have to say that I was blown away. Not only does she sing Bach with great technical virtuosity, controlled within an authentic baroque performance idiom, she actually has a REAL VOICE. What I mean by this is that she is emphatically not of the tonally-undernourished baroque soprano variety, which was pretty much all there was when period performance first hit its stride in the 1980s. A real pleasure to discover an artist of this caliber! And the overall performance is first rate. Stunning!
