Query: Not their best work

I have to tell you, I love Sinatra, I love Jobim, I love Bossa Nova, this album is horrible. I am literally shocked at the response that people are giving this. This product was produced at a time when Bossa was the rage, and every crooner and jazz musician was making Bossa albums. This album introduces nothing new, and the vocals and arrangements are mediocre at best. Really, do not get this album, it is awful.
