A new comedy series about an unlikely friendship, singing, songwriting and the adventures of trying to achieve one's dreams, premiering December 4 (8:00 p.m., ET/PT) on Disney Channel.

Starring are newcomer Ross Lynch as Austin, Laura Marano ("Without a Trace," "Back to You") as Ally, Raini Rodriguez (Disney's "Prom," "I'm in the Band") as Trish and Calum Worthy ("Psych," "Good Luck Charlie") as Dez.
