According to the band's labels Cherry Red Records and Esoteric Recordings, the singer died at his home in Surrey, England on 6th January.
'We are deeply shocked by his passing and will miss his warmth, humour and kindness,' the labels wrote in a statement. '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.'
