New Orleans brass band meets Mardi Gras Indian outfit, Cha Wa, radiates the energy of the city’s street culture. Their album “Spyboy,” a nod to frontman J’Wan Boudreaux’s role in the Golden Eagles, is a modern mix of fiery, toe-tapping sounds. Popmatters describes the band as “a grand gumbo of singing, intoxicating rhythms and deep funk grooves that are impossible to resist.” Cha Wa was nominated for a GRAMMY in the “Best Regional Roots Music Album” category.
