Ray Thomas, flautist, vocalist and founding member of the Moody Blues, died Thursday at the age of 76.

His music label, Esoteric Recordings/Cherry Red Records, said Thomas died suddenly Thursday at his home in Surrey, south of London.

“We are deeply shocked by his passing and will miss his warmth, humour and kindness,” the label said Sunday. “It was a privilege to have known and worked with him and our thoughts are with his family and his wife Lee at this sad time.”
