With every Sinatra album in my collection, I can definitely say these two recording sessions represent the very best of Sinatra's voice. You'd have to listen to Sinatra At The Sands, with the Basie Orchestra and Quincy Jones arrangements to rival this collection. When the Sinatra/Ellington album came out, I had hope it would be a sentinal event. Unfortunately, the song selection was a huge dissapointment and was nowhere near a reflection of Sinatra's caliber of talent.
What makes this collection great is not only his voice, but the arrangements. I can't think of another album that accentuated his persona of that era. His voice was stronger, had a deeper range and was more commanding than the Capital years. He was well past those "only the lonely" years and was full of vigor in the early 60's. Frank was at the top of his game then, with the Rat Pack, the movies, Vegas and Reprise in full swing. I can't imagine any serious Sinatra fan not having this in their collection.
