Jackson Ward is one of the most culturally significant black neighborhoods in the country. The district was known as the Harlem of the South before the 1958 construction of the hotly debated Richmond-Petersburg Turnpike — now Interstate 95 — which split the neighborhood in two and leveled more than 700 houses. The 2nd Street Festival, in its 26th year, celebrates the reason why James Brown name-checked Richmond on “Night Train.” The feel-good funky sound of Midnight Star headlines the festival with performances by Larry Bland and the Volunteer Choir, Plunky and Oneness, Visions Band, No BS Brass! band, Johnny Houston and the Legends and many others. It’s all going down with four stages of live music, plus children’s activities, fashion shows, and food, beer, and artisan vendors. The free event runs Saturday and Sunday, Oct. 4 and 5. venturerichmond.com.
