Out musician Kaki King has written a breakup album with a perfect title: Dreaming of Revenge. Among her fans is Sara Quin of Tegan and Sara, who told AfterEllen.com that King writes "the saddest melodies you've ever heard. The kind of songs you like to fall asleep to, but also have to absorb alone, in case you're moved to tears."

King, 28, has admitted to this, claiming that the best kinds of songs are the sad ones — which must be why Dreaming of Revenge rings so true.

She has also lent her mastery of the guitar to other projects in the past year, including Tegan and Sara's album The Con, the Foo Fighters' Grammy-winning album Echoes, Silence, Patience & Grace, and the score for the film Into the Wild. She also played the role of the lead character's guitar-playing hands in August Rush.

With so much of her time dedicated to making others sound and look good in 2007, 2008 is certainly King's own year. She recently spoke with AfterEllen.com about writing sad songs, why she's the least serious person ever, and working with Tegan and Sara.

AfterEllen.com: Was adding the lyrics and singing on Until We Felt Red and on the new album something you did to become more accessible? It seems like even if it's something you didn't intend to do, it's become that way.
Kaki King: I feel like my other albums are accessible, too, but maybe they're just accessible to me. [laughs] I don't care if I'm accessible or not, but … I haven't been able to really choose what I write or in a certain direction; it just seems to come out a certain way. I mean, I've been writing songs and lyrics to songs since I was a kid, it just kind of happened that I was a solo guitar player.

It wasn't that I was making a conscious decision, like I don't think about fans and things like that when I'm crying and writing a song. It was kind of like, we'll just see how this goes, and it's kind of funny because I actually sing on fewer songs in this new record than I did on the last record. It just seemed like the songs that sound good with lyrics, with vocals.

AE: How did you get involved with working on Into the Wild score?
KK: They brought me in at the last minute with about 10 scenes they had written music for, and they used a couple of songs from my second album in the soundtrack as well.

AE: Have you done film scoring before?
KK: Not on that scale, nothing on that level. It was really great because my contribution to the score wasn't really gigantic, but I was able to come in when they had most of it done, and listening to what they had already done, [I] was able to provide things with Eddie Vedder's aesthetic and at the same time do what I do.

It was a long process, but it was cool to work under that kind of pressure, to say, "We have an hour before we move to the next scene." It's endless pondering and thinking and seeing what works and this and that.

AE: How did you become involved with being the hands of the little boy in August Rush?
KK: The reason why they found me specifically is because I'm a female guitar player, I could redo the part to make it sound better, and I could also fit in the little boy's costume and be the hand double. That's why I think they hired me.

AE: Did you have to do anything to make your hands more boyish or do you just generally have boyish hands?
KK: I don't think I have boyish hands, but a female would have more little boyish hands — that makes sense. But he's supposed to be a street urchin, so they made my fingers filthy. You can't really tell … but my fingers were covered in this fake dirt they have.
