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 27s he was estranged from his family; he lacked confidence and suffered with 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 Seconal by his side. Cause of death was officially given as an accidental overdose of barbiturates, but [drummer] Fito de la Parra believes Wilson committed suicide, at age 27.
