The main character of the show, "Instant Star" (which was cancelled in late 2008). She released 4 album soundtracks for the hit show. Alexz is currently wrapping up her debut CD, which is probably going to be released in 2009. She has an incredible voice, although it is probably edited, considering the fact that most artists' voices are edited down on an album.
Did you see "Instant Star" last night? Alexz Johnson is such a good actress!
