Beyonce church at new orleans

You're referring to the iconic performance by Beyoncé at the 2015 Coachella music festival, which was held at the Empire Polo Club in Indio, California, not New Orleans.

However, I can provide you with some information about the performance, which was a historic moment in music history. Beyoncé's performance, titled "Homecoming: A Film by Beyoncé," was a celebration of historically black colleges and universities (HBCUs) and featured a marching band, drumline, and choir from several HBCUs, including Bethune-Cookman University, Texas Southern University, and Xavier University of Louisiana.

The performance was a tribute to the legacy of HBCUs and the African American experience, and it featured a mix of Beyoncé's hit songs, including "Crazy in Love," "Formation," and "Halo." The performance was widely praised for its energy, choreography, and cultural significance, and it has been credited with helping to increase awareness and appreciation for HBCUs.
