Billboard quotes him in the upcoming book, "1967 - The Complete Rock History of the Summer of Love," as saying, "Jefferson Airplane had the fortune or misfortune of discovering Fender Twin Reverb amps and LSD in the same week while in college."
Founded in 1966, Jefferson Airplane performed at the biggest music festivals at the time including Woodstock, and its second album snagged the third spot on the Billboard 200. (Video via Sony BMG Music Entertainment / Jefferson Airplane)
Kantner is survived by his three children and the other original members of the band.
