Doc Neeson, the lead singer of The Angeles, died early Wednesday morning.
Neeson, 67, died 18 months after being diagnosed with a brain tumor.
He passed away peacefully around 7:15 a.m. local time, sources told the Sydney Morning Herald.
Neeson had undergone surgery to try to remove the rumor but he said earlier this year that it had returned.
“The news is grim, but some people can get through this, and that’s the way I try to think about things,” he told the ABC’s Australian Story.
“So I’m looking forward optimistically to the future.”
Neeson had released his first single in seven years in March, Walking in the Rain.
He performed the song on the SBS show Rockwiz.
The angels formed in 1974 in Adelaide before later relocating to Sydney.
Their hits included “Take a Long Line”, “Shadow Boxer”, and “Dogs Are Talking.”
They were cited by a number of bands, such as Guns N’ Roses, Pearl Jam, and Nirvana, as having influenced their music.
