“Rest in power my dear sister,” LaBelle concluded.

“I love you always!”

“Words are inadequate so I will use few.

We spoke a musical language, music says it best,” she wrote.

Born in Trenton N.J., Dash started her career by creating a vocal group called the Capris.

The group formed a quartet called The Bluebelles, later renamed Patt LaBelle and the Bluebelles.

In 2003, Dash was inducted into the Grammy Hall of Fame.
