Diana Krall: S'Wonderful (studio version, 2001)

I once thought that all the great bossa nova singers were from Brazil, but Krall has forced me to alter my opinion. Thirty years ago, João Gilberto recorded this same Gershwin standard adapted to the bossa beat (also with a Claus Ogerman arrangement), but Kralls version can proudly stand alongside this esteemed predecessor. Yet Krall never stoops to imitate, and she makes this song her own. When they write the textbook on relaxed singing, this should be included on the companion CD.
