"Roxanne" covered by Dilana
"Time after time" covered by Dilana
These clips are from the mediocre reality show Rockstar Supernova. The show worked like American Idol except that when the contestansts were narrowed down to two the judges (a group of ex-rock band members) picked the winner. Dilana - the runner up - I think has an amazing recording voice.
And this cover of "Mother Mother" by Tracy Bonham was probably her strongest performance on the show.
