Cult singer-songwriter Daniel Johnston has died aged 58.
The American musician passed away following a heart attack, Johnston's former manager Jeff Tarkakov told The Austin Chronicle newspaper.
Despite battling chronic mental illness, Johnston had an influential career as a singer-songwriter.
He was a significant figure in the lo-fi and alternative music scenes after rising to underground fame in the 1980s.
Johnston became known to a wider audience when Nirvana's Kurt Cobain started wearing one of his t-shirts around 1992.
In 2005, Johnston was the subject of the powerful documentary The Devil and Daniel Johnston.
Fans admired Johnston for his simple, sincere and childlike music.
High-profile artists including Beck, Flaming Lips, Yo La Tengo, Death Cab for Cutie and Eels have covered his songs.
Tributes have been paid to the late singer-songwriter on Twitter.

RIP Daniel Johnston. I'm old enough to remember when he still had individually recorded casettes for sale on the counter at Sound Exchange, if not to have had one handed to me in person on the Drag. Too pure for this world. #Austin— Wiley Wiggins (@wileywiggins) September 11, 2019
