Query: Frank Sinatra and Nelson Riddle At the Top of their Game !

Those who in earlier reviews have said that Sinatra wasn't engaged when recording this album should have another listen. FS and his favorite arranger Nelson Riddle are both in TOP form in this SENSATIONAL swinging album that contains more knock-out numbers that any other album Sinatra ever recorded. Every Riddle arrangement on this album is a "10" -- from the opening WHEN YOU'RE SMILING to the closing YOU DO SOMETHING TO ME. The three add-on songs in the later re-release of this album were not part of the original 12-song LP. In between these two bookend songs, Sinatra and Riddle soar to heights that other singers and arrangers can only dream of. Listen to Frank on BLUE MOON, SEPTEMBER IN THE RAIN and I CONCENTRATE ON YOU. You'll never hear singing like that again in your lifetime. This is swinging pop music at its absolute best with two masters creating a musical nirvana that likely will never be equaled.
