I'd reckon that anyone who gives this richly layered album only one star, as being someone who has probably fallen into the trap of thinking because it's deceptively relaxed that it's also superficial. Unless completely cloth eared , that's transparently not the case. Yes, it can be heard as what is now referred to as being 'elevator music' if that's as far as anyone wishes to dig. But more attentive listening with a sympathetic ear, then the richness of the underlying structures and interplay between players becomes apparent. For instance there's the leading jazz trombone along with flute, and piccolo played in parallel to the swinging melody of guitar and piano on most tracks. My only criticism is that there's only one track with Jobim singing.- he's pretty good at delivering his own material.This is an album of many pleasing aspects and recommended listening.
