In the 1940s and ‘50s, Boston’s South End was flush with jazz clubs—the High Hat, Savoy Ballroom, Chicken Lane. Wally’s was founded in 1947 by Joseph L. Walcott, said to be the first African American to own a nightclub in New England. Today, this teeny venue serves up jazz (but no food) 365 days a year. There’s a jam session from 6 to 9pm every evening, often featuring students from neighboring Berklee College of Music, and then jazz, funk, blues, or Latin salsa from 9:30pm to 2am.
