True jazz lovers argue that Krall only has reached such a high popularity, as she indeed has, thanks to a shrewd marketing. That argument could be used just as effectively on singers like Norah Jones. As for Krall, she has a soft and sexy voice that appeals to many mainstream listeners who aren't concerned so much about jazz and how she plays the piano.
The marketing people behind Diana Krall's music is of course tempted to polish and popularize the music as much as possible. As is seen at once when looking on the cover of _The Look Of Love_, this is what they have done. The album begins with S'Wonderful played with bossa nova rhytms and a laid back vocal. The whole album is actually very much inspired by bossa nova, which provides a romantic atmosphere - again suiting Krall's looks and voice and the many listeners.
On Krall's first albums, _Stepping Out_, _Only Trust Your Heart_, and _All For You_, the romantic atmosphere is somewhat missing. The marketing wasn't so much aware of her commercial oppertunities that they regulated her own sound. The albums as a result sound more raw, resulting in more piano from Krall and more jazz-like compositions and atmosphere. What i miss, though, when hearing her earlier work, is exactly what _The Look Of Love_ has to offer: the richness of the sound, the polished sound quality, the not so jazz-like songs etc. The intro on I Get Along Without You Very Well for instance, is beautiful and heartbreaking. So is all other songs on the album. I understand people's objections to Krall's music, but at the same time I feel that the music is gripping, moving, meaningful and whatever words there is to express good music.
