Essra Mohawk (/ˈɛsrə/; born Sandra Elayne Hurvitz; April 23, 1948 – December 11, 2023) was an American singer-songwriter who recorded a dozen albums.
As Sandy Hurvitz, she was then discovered by Shadow Morton, who placed her songs with both the Shangri-Las ("I'll Never Learn") and the Vanilla Fudge ("The Spell That Comes After").
While living in New York City in 1967 she met Frank Zappa, who persuaded her to perform for a short time with the Mothers of Invention and then signed her to his Bizarre Records production company.
While he initially helped to produce her first album, he left the project and assigned it to woodwind player and keyboardist Ian Underwood.
Hurvitz opened for Procol Harum when they performed at the Cafe Au Go Go in 1967, and Keith Reid wrote "Quite Rightly So", which appeared on their second album Shine On Brightly, for her.
The album featured contributions from CSN&Y drummer Dallas Taylor and former Rhinoceros members Doug Hastings and Jerry Penrod.
“We got there in time to see the last verse of the last song of the last act of the first night, and then the stage went dark before we got to it from the parking lot,” she recalled in a 2009 video interview.
In addition, Mohawk sang the theme song to "Teeny Little Super Guy", a regular segment on Sesame Street during the 1980s.
