Leonard Charles Williams (born February 16, 1945)[1] is an American singer-songwriter and musician, best known as the lead vocalist for the soul/funk group Tower of Power in the early 1970s.

[2] Learning to play the trumpet in elementary school fueled his interest in music; his skills as a vocalist were first nurtured by singing in gospel choirs and groups around the Bay Area.

He worked with several notable artists, such as Sly Stone, Andraé Crouch, Billy Preston and members of the Hawkins family, Edwin, Walter and Tramaine.

During his two years with the group, Williams participated in three albums: Back To Oakland, Urban Renewal and the gold LP Tower of Power.

In 1986, he was invited to sing vocals on "Don't Make Me Wait For Love", a track from Duotones, a multi-platinum recording by Kenny G. The song became a Top 20 Billboard Hot 100 and R&B hit the following year.
