S
S is the moniker of ex-Carissa's Wierd singer/songwriter Jenn Ghetto. By herself Jenn shows the more raw side of Carissa's Wierd best seen on Ugly But Honest as opposed to the more polished later work (though some songs like Sofisticated etc sound pretty much like S songs.) Her songs are very dark and even more raw and intimate than her non-solo work as unbelievable as that sounds.
She has two albums out Sadstyle and Puking and Crying. The former is much more of a raw just her and electric guitar type album while the latter has other people involved and has more going on but I don't think the songs are as strong on it. I'm pretty sure she's working on a third one and from what I've heard it's probably going to be her best yet.
