The mark of a great fado singer is that she can convince you of anything: That her heart is breaking. That her desire is so fervent she could just die. And most of all, that anything can be a fado. Ana Moura is just such a singer, and she proves it with an album that turns anything and everything into brooding passion: The oompahing but sexy "Amor Afoito." Joni Mitchell's "A Case of You." Even English tunes like "Dream of You" that verge on smooth jazz (Herbie Hancock on keys helps). Because a great fadista can also make you fall hard, even for songs you aren't sure you like.
