Fellow Pitch Perfect 2 cast members Anna Camp and Brittany Snow appear in Dean’s ‘Crazy Youngsters’ video, as well as Vine users Princess Lauren and AmyMarie, plus many YouTube stars, including a cameo by Flula Borg.
Dean possesses a mezzo-soprano range. Her vocals were described by Billboard as “raw, energetic vocals cover a wide range: from club banger to melodic doo-wop/hip-hop. The songwriter’s voice is pitched dead center between two artists. The first is frequent collaborator Rihanna…the other is Nicki Minaj when she sings.”
In a 2012 article in The New Yorker, Dean described her preferred method of songwriting: “I go into the booth and I scream and I sing and I yell, and sometimes it’s words but most time [sic] it’s not…and I just see when I get this little chill [on her upper arm, below the shoulder] and then I’m, like, ‘Yeah, that’s the hook.”
Dean voiced two of the characters in the fourth film in the Ice Age franchise, Ice Age: Continental Drift, and also wrote a song for the movie, entitled “We Are (Family)”. – Wikipedia
