"The Glee Project" returns for its second season as the competition series searches for another singer (or more) to make guest appearances on the popular Fox series"Glee." Ryan Murphy, co-creator of "Glee," once again judges the hopefuls, casting director Robert Ulrich and choreographer Zach Woodlee return to mentor the contestants and assist Murphy, while vocal coach Nikki Anders, who mentored the season-one contestants, joins in the deliberations in season two. As in season one, "Glee" series regulars serve as guest mentors throughout the season. Among the 14 singers competing are Mario, who has been blind since the age of 9; bartender Abraham, who postponed his admission into law school to pursue his entertainment dreams; former "America's Got Talent" contestant Dani; and Ali, who is paralyzed from the chest down and has used a wheelchair since a young age.
