Harlem in New York City has been jumping with jazz for over 100 years, and it’s still going strong if you know where to find it. Clubs, restaurants, and jazz joints are listed in guidebooks, but I decided to get the real deal on uptown jazz with a tour guide who’s got all the information — and then some! She’s my friend, and she invited me to tag along on one of her Friday night ’Round Midnight Tour jaunts through Harlem.
