After co-writing and producing hits for the likes of Miley Cyrus (“We Can’t Stop”) and Rihanna (“Pour It Up”), these brothers from St. Thomas, Virgin Islands stand ready for their time in the spotlight. Caribbean rhythms and pop hooks freely intertwine, creating a hip-loosening island confection. “Locked Away” jumps with a dancehall riddim that’s bolstered by a chorus from Adam Levine. “Broadway” and “Save My Soul” will make reggae fans smile with nods to Barrington Levy and Bob Marley. And don’t miss their grind-or-die tale “Our Story,” 10 minutes of R. City breaking down their road to a better tomorrow.
