Canned Heat enjoyed considerable artistic and commercial success, crowned by an appearance at Woodstock in 1969. But guitarist Al "Blind Owl" Wilson was a troubled man. Like many in the 27 Club, he was estranged from his family; he lacked confidence and suffered from depression. One of his eccentric habits was sleeping outdoors, as he did at vocalist Bob Hite's house in Los Angeles on the last night of his life. Wilson's body was found in Hite's yard on September 3rd, 1970. His hands were crossed over his chest and there was a bottle of the barbiturate Seconal by his side. Cause of death was officially given as an accidental overdose of barbiturates, but drummer Fito de la Parra has said he believes Wilson committed suicide.
