Funk. New Orleans horns. Pop. Conscious hip hop. Dancehall… LowDown Brass Band brings all those sounds together to create a sound that, in their own words, could only have come out of Chicago. Before they play Thalia Hall with Galactic on 3/25, Billa (MC) and Shane (vocals, trumpet, keyboards) jumped on to talk about an album that’s built for our upcoming better weather: “LowDown Nights.”
