The 36-year-old Timmy Matley had been battling skin cancer for nearly two years, and his bandmates are devastated by his passing.
Mattley joined the London-based five-piece vocal harmony group in 2010. He was diagnosed with cancer in 2016, but the cause of death is yet to be determined.
As reported by Mirror, reports indicate that Matley 'died after falling from a balcony,' but neither his bandmates nor family have confirmed the rumor.
The Overtones took to Twitter on April 11, 2018, to inform their fans of Matley's passing. They said the news was heartbreaking and thanked their fans for the support.
'It is was the greatest sadness that we have to announce that our dear friend and brother Timmy has passed away.'

According to Mirror, Matley was diagnosed with stage three malignant melanoma after he found a lump under his arm in the summer of 2016.
The news was devastating to him and his family because he displayed no symptoms before the diagnosis. He also had to cancel several tours.
Mattley underwent surgery to remove some of the cancerous cells. He thought that the hardest part of the journey was behind him, but sadly that wasn't the case.
Soon after the surgery, more lumps were discovered around his collarbone and neck. He took time off from the band to focus on his treatment.
He was tested regularly and his scans looked 'really positive.' He was happy to inform his fans that cancer had regressed and said he was blessed to 'be one of the lucky ones.'

He expressed his gratitude many times for being surrounded by people who truly cared about, and who supported him during his illness.
