Both these albums are beautiful, and cheap.
Astrud Gilberto performs the canonical version of The Girl From Ipanema (accompanied by her husband Joao Gilberto and Stan Getz), and it's easily worth it just for that, but there are another fifteen tracks, most of them achingly beautiful. Aching is probably the apropos word; Astrud is (according to the liner notes) "the mistress of that uniquely Brazilian mood Saudade" (longing)
A brilliant collection of Ella Fitzgerald tracks, accompanied by various killer orchestras; the outstanding track here is her rendition of Mack the Knife live in Berlin, where she forgets the words after two verses and just starts riffing. If this doesn't bring a smile to your face, you should check your pulse: you're probably already dead.
