I've never been too interested in collaborations. That sounds kind of selfish. I think at one time I wanted to work with Tori Amos a lot, but that never happened. I took an a capella song of hers and made my own music for it. That's enough of that.
SOS is one of the oldest songs on the album.
I wrote it while I was still in Santa Fe. It's definitely one of the moodier songs on the album. The sample is of a German guy I met in Santa Fe who was telling me his story about his experience hitch hiking from LA to Santa Fe. Upon his first arrival to the states. I thought the recording of his voice fit well with the mood of the song.
