Abstract - In the visual arts, a work is considered abstract when an artist focuses more on elements such as color, line, shape, tone, and pattern, and is less concerned with representing a subject from the real world in an immediately identifiable way. While often the image has a source in the natural world, it’s forms may be simplified, distorted, or exaggerated in some way.

Historically, the Lower East Side stretched from the East River west to Broadway, and from Canal Street up to 14th Street. Before the influx of eastern European Jewry, the area had served earlier immigrants, including many from Ireland and Germany. By 1900, as new immigrants from eastern and southern Europe moved in, most of the earlier inhabitants relocated to other parts of the city. In 1915, an estimated 350,000 Jews (along with about 150,000 non-Jews) lived on the Lower East Side—an area of less than two square miles.

Tenements - The word “tenement” originally referred to any rented dwelling that housed three or more separate families. Today, the term is generally used to describe the kind of overcrowded urban apartment buildings that many immigrants lived in during the late 19th and early 20th centuries. Tenement conditions were often harsh, with poor ventilation and sanitation. A series of housing reform laws, however, gradually improved conditions somewhat by the 1930s.

Aspiring musicians and performers often visited this tree and swore by its magical powers.
