Welsh rock guitarist Robert "Tich" Gwilym died in a house fire in Cardiff over the weekend, South Wales Police have confirmed.
Mr Gwilym was well-known in the Welsh music industry
The 54-year-old musician, from Penygraig near Tonypandy, was in a loft conversion at a house in the Pontcanna area when the fire broke out.
He will be most remembered for his unique interpretation of the Welsh national anthem on the electric guitar.
Two other people were treated in hospital after the blaze on Sunday.
The body of Mr Gwilym was found on the second floor of the building.
He regularly performed with Geraint Jarman, who said Mr Gwilym had "raised the level and the standard of the music in Wales".
"The guitar was always a part of him and it was never far away - he learnt how to make guitars and he knew everything about them," he said.
"He was kind and he would have done anything."
Mr Gwilym also frequently performed alongside singer Heather Jones, who described the death as "a huge loss".
"I just can't accept the fact that he has gone - nobody can understand what's happened - it's so sad," she said.
Three fire crews were sent to the blaze which took hold on the first floor and landing just before 0800 BST on Sunday morning.
The cause of the blaze is under investigation by police.
