John Warren Geils Jr, the artist known professionally as J Geils who gave his name to the 1980s rock group he founded, The J Geils Band, was found dead in his Massachusetts home yesterday. He was 71.

Groton Chief of Police Donald Palma Jr. confirmed the death, adding in a press release that a preliminary investigation “indicates that Geils died of natural causes.” Palma said that because the death was “unattended,” it will be investigated but “foul play is not suspected at this time.” He said Groton police went to the home around 4 p.m. ET in response to a well-being check and found Geils unresponsive.

The J Geils Band’s third album, Freeze Frame, was Number 1 for four weeks in the US in 1983, and its hit song, Centerfold, was Number 1 for six weeks on the Billboard Top 100; it was also a Number 1 in Canada and Australia and a Number 3 in the UK.
