Al Jarreau, 7-time Grammy-winning jazz, pop, and R&B singer has passed away at the age of 76, according to TMZ.

A message from Jarreau's official Twitter account indicates that he "passed away this morning. He was in the hospital, ... kept comfortable by his wife, son, and a few of his family and friends." So far, there is no report of the cause of the singer's death, though he had suffered respiratory and cardiac issues over the last few years.

Jarreau released his debut album, We Got By, in 1975. He was nominated for over dozen Grammy awards over the course of his career, and won seven, the first of which for his 1977 live album Look To The Rainbow. He is well known for his song "Moonlighting," which served as the theme song for the 1980s sitcom of the same name. As TMZ suggests, Jarreau's son says that his father sang the song to one of his nurses while he was in the hospital.

 The Roots' Questlove has shared a tribute to Jarreau on Instagram, calling him one of "the most creative vocalists ever."
