It might not even be arguable that the greatest achievement ever in American popular music is Ella Fitzgerald’s Songbook series. The concept was simple: One album (sometimes a double album) dedicated to one great American songwriter, or songwriting team. The music for each album would have a single band with a single conductor-arranger. That way a consistent sound was achieved throughout, with the focus being on Ella’s interpretation of the lyrics. The execution was flawless, of course — we’re talking Ella here.
Turns out she can make a Christmas record pretty good, too.
