Singing performances make 'Pitch Perfect' aca-mazing

‘Glee’ meets ‘Bring It On’ with the sassy swagger of ‘Clueless’ in Jason Moore’s unabashedly feel-great musical comedy about an all-girl a cappella group hoping to pitch slap their well-rehearsed rivals at a national singing competition.

‘Pitch Perfect’ delivers a menagerie of memorable characters who are determined to chart a course through life with lyrical guidance from Madonna, Kelly Clarkson and Jessie J.
