Matthew Davidson found out Friday he had made the final cut for Kidd Kraddick's Rock Camp. By Sunday, he was in Dallas for rehearsal. By Monday, he had learned a new song along with his band mates and performed it live on air for over 80 markets on Kidd Kraddick in the Morning. That wouldn't be bad for a 30 year old... Here's the kicker... Matthew is 13 and he's already got to use Jenna's mic and met Tim Halperin of American Idol fame.
