He's got the blues

While bands from Chicago get loud in J.P., fado will seduce listeners in Davis Square. Johnny D's is hosting Helder Moutinho, who sings fado, a traditional style of Portuguese music that's often about love and loss. It's usually performed by women, but Moutinho proves men have their own reasons to sing the blues. 8:30 p.m. $12. Johnny D's, 17 Holland St., Somerville, 617-776-2004. johnnyds.com
