Whitney Claire Kaufman

Globe Correspondent / November 29, 2007

“Mamma Mia!” – the fizzy valentine to disco-era surround-sound featuring the music of ’70s popsters ABBA – has landed at the Colonial Theatre.

Boston’s opening night – the national touring company’s fourth ascent on the city so far – featured two understudies taking over lead roles, and it was still a knockout. Don’t be surprised if Whitney Claire Kaufman eventually graduates to one of the eight standing productions in locales as far-flung as Moscow and Las Vegas. With her pure, clear voice – gentle or forceful as called for, but always beautifully placed – she really deserves to vault straight to Broadway. Plus, her acting is as compelling as her singing.
