Firstly if you're hesitating over purchasing this album, DON'T! just buy it. It really is a no brainer at this price, this was my first purhase of O'day's material, as others have said its a great introduction to her talents.
Four great albums....well 'The Lady Is A Tramp' album maybe not up to par with the rest IMO; as stated by another reviewer-Nikica Gilic with whom I do agree mostly. Its not pure jazz but still listenable the track 'Love for Sale' one of the highlights.
The other three albums are great, I listen to this compilation alot, there's a real mixture, fast tempos- especially on 'Anita Sings The Most' fantastic album. From this wonderful album personal highs include; 'Love me or leave me' and 'Them there eyes' pure class, then slower numbers such as the smooth, almost haunting 'Tenderly' which for me is my favourite song on this comp, the brilliant 'Stella by starlight' being another gem.
I could go on there's so much to choose from here, even if you only like one of the albums; though I can't see how, you're still getting a real bargain.
Some people accused her of ripping off the likes of Billie and Ella, which I don't agree, she holds her own, whilst she admired Billie Holiday, inspired by even, whats wrong with that many great artists if not all are influenced by others. She has her own distinct 'sassy' sound, which seduced me anyway!
My review might be a bit messy, all over the place, my apologies! Others on here probably put it better haha. Anyway let your own ears persuade you!
I did write a review some months back now, but for some reason, technical glinches on amazon error prevented its submission, got round to writing it again as I think its worthy of it.
