Cha Wa

New Orleans brass band-meets-Mardi Gras Indian outfit Cha Wa radiates the energy of the city’s street culture. “My People,” the band’s Grammy-nominated follow up to their (also Grammy-nominated) album “Spyboy,” feels like pure joy, a distillation of generations of New Orleans expression. But it also never fails to remind us how hard-won that joy was and still is: not least in the tense, funky and explosive title track, with its declaration “My people, we’re still here.”
