Following the Jefferson Airplane reunion , Slick retired from the music business . During a 1998 interview with VH1 on a '' Behind the Music '' documentary featuring Jefferson Airplane , Slick , who was never shy about the idea of getting old , said that the main reason she retired from the music business was , " All rock-and-rollers over the age of 50 look stupid and should retire . " In a 2007 interview , she repeated her belief that , " You can do jazz , classical , blues , opera , country until you 're 150 , but rap and rock and roll are really a way for young people to get that anger out " , and , " It 's silly to perform a song that has no relevance to the present or expresses feelings you no longer have . " Despite her retirement , Slick has appeared twice with Kantner 's revamped version of Jefferson Starship ; the first came in 1995 when the band played at Los Angeles 's House of Blues , as documented on the live album '' Deep Space/Virgin Sky '' . The second was for a post-9 / 11 gig in late 2001 , during which she came on the stage initially covered in black from head to toe in a makeshift burqa . She then removed the burqa to reveal a covering bearing an American flag and the words " Fuck Fear " . Her statement to fans on the outfit was : " The outfit is not about Islam , it 's about oppression ; this flag is not about politics , it 's about liberty . " After retiring from music , Slick began painting and drawing . She has done many renditions of her fellow 1960s musicians , such as Janis Joplin , Jerry Garcia , and others . In 2000 , she began displaying and selling her artwork . She attends many of her art shows across the United States . She has generally refrained from engaging in the music business , although she did perform on " Knock Me Out " , a track from '' In Flight '' , the 1996 solo debut from former 4 Non Blondes singer , and friend of daughter China , Linda Perry . The song was also on the soundtrack to the film '' The Crow : City of Angels . '' Slick released her autobiography , '' Somebody to Love ? A Rock and Roll Memoir '' , in 1998 and narrated an abridged version of the book as an audiobook . A biography , '' Grace Slick , The Biography '' , by Barbara Rowes , was released in 1980 and is currently out of print . In a 2001 '' USA Today '' article , Slick said , " I 'm in good health and people want to know what I do to be this way ... I do n't eat cheese , I do n't eat duck — the point is I 'm vegan . " However , she admitted she 's " not strict vegan , because I 'm a hedonist pig . If I see a big chocolate cake that is made with eggs , I 'll have it . " In 2006 , Slick suffered from diverticulitis . After initial surgery , she had a relapse requiring further surgery and a tracheotomy . She was placed in an induced coma for two months and then had to learn to walk again . Also in 2006 , Slick gave a speech at the inauguration of the new Virgin America airline , which named their first aircraft '' Jefferson Airplane '' . In 2010 , Slick co-wrote '' Edge of Madness '' with singer Michelle Mangione to raise money for remediation efforts following the BP oil spill . Grace also sang background vocals on the song and is clearly audible in the middle of the song singing , " On the edge of madness . " Slick has been married twice — to Gerald " Jerry " Slick , a cinematographer , from 1961 to 1971 , then to Skip Johnson , a Jefferson Starship lighting designer , from 1976 to 1994 . She has one child — a daughter , China Wing Kantner ( born January 25 , 1971 ) . China 's father is the former Jefferson Airplane guitarist Paul Kantner , with whom Slick had a relationship from 1969 to 1975
