BATTLE OF THE BANDS! The Arts-Angels want to debut their first song in concert, and Willa Burch is offering her amazing, mansion-size apartment with its built-in ballroom as the place to do it. All of the Arts-Angels are tempted to accept the offer--all except Gina, who doesn't want to owe Willa any favors (or worse, feel like Willa owns the band). But when their rivalry with Uncouth Youth explodes, it looks like the Arts-Angels will have to take up Willa on her offer--or break up! The Arts-Angels may be over before they even begin. . . .
