If the last name sounds familiar, that’s because she’s the daughter of renowned folk singers Loudon Wainwright III and Kate McGarrigle, as she’s the brother of singer-songwriter Rufus Wainwright, who has one of the most unique voices in modern music. Martha, herself a singer-songwriter who sings and plays guitar, has established a very noteworthy career on her own. For this tour -- which includes Myron’s -- she’s celebrating the 20th anniversary of her acclaimed self-titled album, which famously has a very profane song about her father on it, and features her brother and mother as well. She and her band are expected to play the album in full at Myron’s.
