The musician was confirmed to have died from a heart attack aged 58 by his manager Jeff Tartakov last night (11 September).

His career saw Johnston release 17 albums. According to The Guardian, Johnston said last year that he had been recording material for a new album "for years".

In the statement posted to socials, Johnston's family writes, "The Johnston family is deeply saddened to announce the death of their brother, Daniel Johnston. He passed away from natural causes this morning at his home outside of Houston, Texas."

Johnston's older brother Dick Johnston said of his brother's passing, "I always wanted Danny to feel like his own person, and in control of his own life. Since beginning to work and travel with him in about 2003, we gratefully were able to travel the entire globe for over a decade to get out before the fans. He was always, everywhere, warmly received and he at least knew he was well loved. Health issues have plagued us for years, but I’m glad for the time we had."

Tom Gimbel, his manager for over 25 years added, "I am so saddened by the news of Daniel's passing. It has been the greatest honor and privilege of my professional life to work with Daniel Johnston - someone who I consider to be one of the greatest songwriting geniuses of our time. In our time together Daniel was more than an artist; he was a friend, he was family. I will miss him greatly but will smile every time I hear his songs."

Musicians and labels around the world have been paying tribute to the late musician on social media.
