Three alumnae of a Rochester-based nonprofit will tour with Aaron Carter this summer. Yes, the '90s, pre-teen, pop star Aaron Carter... except now, he's all grown up.

Jackie Ferreira, 16, of Dartmouth, along with South Coast residents Tori Kalisz, 15, and Olivia Nunes, 17, of Acushnet, will tour as the girl group Sequence this August. The Philadelphia and New York stops with Carter mark the girls' first national tour.

The three met through Rochester-based nonprofit Voices in Time, which teaches singing and choreography to five- to 18-year-olds, and gives back to the community with more than 50 performances each year, according to its Facebook page. The nonprofit is run by Rochester resident Sharon Jensen.

Through Jensen's connections, the girls were able to land a spot in the tour.

"The event organizer contacted Sharon Jensen. It's the right age. The right demographic. [The girls] are spreading the right message," said Marlene Kalisz, who is Tori's mother and Nunes' aunt.

"Voices in Time taught us to give back to the community and use our talents as a team," said Ferreira. The girls have performed at fundraisers like the Run to Remember 5K and the Special Olympics, as well as at sporting events, nursing homes, and festivals including New Bedford's AHA! Night.

"Most recently, at Miss Inspirational [a pageant for young women with special needs, held at Old Rochester Regional High School], we volunteered to help the contestants get ready," Ferreira noted.

The teenagers can't ignore the milestones in front of them. Sequence will sing the "National Anthem" at the July 3 Pawtucket Red Sox game, will perform at the Northeast Youth Music and Arts Festival on September 10, and, of course, there are bragging rights to opening the Summer Nights Tour for headliner Aaron Carter.

Their first single, "All the Time," will be released on June 15. The accompanying music video will be released during a premiere party at Striker's Sports Bar & Grill (66 Hathaway Road, New Bedford) on June 17, 2 - 4 p.m.

The girls are looking forward to producing more music, and expressed interest in writing their own songs. Visit them online at www.facebook.com/SequenceGirls.
