All My Life – K-Ci & JoJo (1998)
This American duo, comprised of brothers Cedric “K-Ci” Hailey and Joel “JoJo” Hailey, was a side-project while part of the R&B/hip-hop quartet Jodeci. K-Ci & JoJo found greater mainstream pop success with this chart-topper and a few additional hits. Their latest US release came out in 2002, and a Japan-only album was issued in 2008. Officially, Jodeci has been on hiatus since this side project blossomed, but they still collaborate occasionally, and there were rumors of a Jodeci reunion. In the meantime, K-Ci & JoJo continue to perform for their dedicated fan base.
