Not many memoirs are generational events. But when Sly Stone, one of the few true musical geniuses of the last century, decides to finally tell hislife story, it can’t be called anything else.

As the front man for the sixties pop-rock-funk band Sly and the Family Stone, a songwriter who created some of the most memorable anthems of the 1960s and 1970s (“Everyday People,” “Family Affair”), and a performer who electrified audiences at Woodstock and elsewhere, Sly Stone’s influence on modern music and culture is indisputable. But as much as people know the music, the man remains a mystery. After a rapid rise to superstardom, Sly spent decades in the grips of addiction.

Now he is ready to relate the ups and downs and ins and outs of his amazing life in his memoir, Thank You (Falettinme Be Mice Elf Agin). The book moves from Sly’s early career as a radio DJ and record producer through the dizzying heights of the San Francisco music scene in the late 1960s and into the darker, denser life (and music) of 1970s and 1980s Los Angeles. Set on stages and in mansions, in the company of family and of other celebrities, it’s a story about flawed humanity and flawless artistry.

Written with Ben Greenman, who has also worked on memoirs with George Clinton and Brian Wilson, and in collaboration with Arlene Hirschkowitz, Thank You (Falettinme Be Mice Elf Agin) is a vivid, gripping, sometimes terrifying, and ultimately affirming tour through Sly’s life and career. Like Sly, it’s honest and playful, sharp and blunt, emotional and analytical, always moving and never standing still.
