DETROIT (AP) — Folk music veteran and Oscar-winning singer-songwriter Buffy Sainte-Marie is among the headliners of a festival celebrating the musical and cultural diversity of Detroit.

The Canadian singer and Native American activist, who was part of the 1960s North American folk scene, is scheduled to perform July 15 at the Max M. Fisher Music Center as part of the 26th Concert of Colors .

Sainte-Marie shared an Oscar in 1983 for the original song, "Up Where We Belong," which was featured in "An Officer and a Gentleman." She continues to release music and garner awards.

The multi-day, multi-venue event will run July 11-15. It again features the Don Was Detroit All-Star Revue led by Was, a nationally renowned musician and producer with Detroit roots.

All performances are free and open to the public.
