Born in New York in 1946 and raised in New Jersey, John Warren Geils Jr. of his full name was found unconscious by emergency services at his home in Groton, Massachusetts, police said . An inquiry was opened into the causes of his death.
The band J. Geils appeared in the mid-60s with a rock-fueled rhythm and blues-style rock. One of the most popular American bands of the 1970s, he is highly regarded for his stage performances. In 1982-1983, he had secured the raising of a European tour of the Rolling Stones.
The training original also included J. Geils (guitar), Peter Wolf (vocals), Seth Justman (keyboards), Dany Klein (bass), “Magic” Dick (real name Richard Salwitz, harmonica) and Stephen Jo Bladd (drummer).
Tensions between Geils and Seth Justman and Peter Wolf, the authors of much of the band’s music, led to his dissolution of the band in 1985.
Withdrew to Groton, J. Geils, who continued to play occasionally jazz and blues, had then discovered a passion for the restoration of race cars, according to AutoWeek.
