According to reviewers' opinions on Bons Amigos they seem to be everything from confusing to downright hostile. BONS AMIGOS is a band that joins certainly Gentle Giant-like vocal harmonies and a similar attraction to medieval and classical motifs.
What do we think is that Bons Amigos is a wonderful album from a very fresh and talented Brazilian band. Every song is a joy to listen to… from Tool like folk mannerisms to classical guitars to much more “proggy” rock, these guys have a lot of interesting musical ideas, mellow, melodic prog with a lot of melodic (NOT atonal/modern) classical influence in it.
