Although one of the city's oldest neighborhoods, with many elegant Federal-style homes, Southwest was primarily a vast slum. Most buildings were small, in extensive disrepair, and lacked both electricity and running water. The alleys were full of one- and two-story shacks, and nearly every dwelling was overcrowded. Gaye and his friends nicknamed the area "Simple City", owing to its being "half-city, half country".
