A cappella group, Naturally 7 returns to the Ridgefield Playhouse on Sunday, Sept. 15, at 7:30 p.m. John Jay High School A cappella group The Rolling Tones will open. Naturally 7 not only sings, but also creates every backing instrument heard on its songs. The band rose to prominence in 2007 after their video of the group singing Phil Collins\u2019 In the Air Tonight on a Paris subway train went viral on YouTube. After Michael Bubl\u00e9 tapped the group as his worldwide touring partner, Naturally 7 has since headlined the Playboy Jazz Festival, played London\u2019s Royal Albert Hall, performed at the BET Honors for Herbie Hancock, and were invited to sing at Quincy Jones\u2019 75th birthday party in Montreux, Switzerland. They most recently performed on CBS\u2019 World\u2019s Best earlier this year with their rendition of Coldplay\u2019s Fix You. The band returns to The Ridgefield Playhouse with their 20th anniversary tour, part of Pepsi Rock Series powered by Xfinity.
