"With a soft tenor voice, and accompanied by his delicate guitar playing, and skilfully integrated synthesised wind instruments, Santanna sings dreamily in praise of nature and our place within it. He sings in Portuguese, English and French, in a manner that soothes: these are incantations as much as protest songs. In "La biosphère", he contrasts the sauvage - the wild rather than the savage - with the "civilised", and the choice we face between embracing life or death ... The poetic and intellectual sophistication of the album is carefully framed within a musical context that is beguiling in its almost child-like simplicity. There is nothing overdone or baroque about Santtana's songs. As in so much of the best Brazilian music, the spirituality is well grounded in lilting samba rhythms and a delicacy overflowing with magic".
