Question: Who is the sister of the performer who wrote the lyrics to L.A.?

full_context: Document 1: Time Fades Away: Time Fades Away is a 1973 live album by Canadian musician Neil Young. Consisting of previously unreleased material, it was recorded with The Stray Gators on the support tour following 1972's highly successful "Harvest". Due to Young's dissatisfaction with the tour, it was omitted from his catalogue and not released on CD until 2017.
Document 2: L.A. (Neil Young song): Johnny Rogan in his "Complete Guide to the Music of Neil Young" tells us that "L.A." was "Young's fantasy vision of the destruction of Los Angeles. There is an underlying glee in his apocalyptic vision that is both intriguing and disconcerting." Rogan also suggests that the song may have been written by Young a full five years before it was debuted during his 1973 "Time Fades Away" tour. Rogan talks about the song at greater length in the book "Neil Young: Zero To Sixty".
Document 3: Loser (Beck song): Referred to as a ``stoner rap ''by AllMusic's Stephen Thomas Erlewine, the lyrics are mostly nonsensical. The song's chorus, in which Beck sings the lines`` Soy un perdedor / I'm a loser baby, so why do n't you kill me?'', is often interpreted as a parody of Generation X's ``slacker ''culture. Beck has denied the validity of this meaning, instead saying that the chorus is simply about his lack of skill as a rapper. Jon Pareles wrote in The New York Times that`` The sentiment of 'Loser' (...) reflects the twentysomething trademark, a mixture of self - mockery and sardonic defiance'', noting Beck's ``offhand vocal tone and free - associative lyrics ''and comparing his vocals to`` Bob Dylan talk - singing''. After its recording, Beck thought that the song was interesting but unimpressive. He later said, ``The raps and vocals are all first takes. If I'd known the impact it was going to make, I would have put something a little more substantial in it. ''The relationship between Beck and Stephenson soured after the release of`` Loser'' as a single. Stephenson regretted his involvement in creating the song, in particular the ``negative ''lyrics, saying`` I feel bad about it. It's not Beck the person, it's the words. I just wish I could have been more of a positive influence.''

It missed the "Billboard" Hot 100 chart completely, but over time has become a staple of his performance repertoire. Both it and "Sugar Mountain", its B-side recorded live at the Canterbury House in Ann Arbor, Michigan, were released on album together for his 1977 compilation, "Decade".
