When his drummer Sonny Greer was invited to join the Wilber Sweatman Orchestra in New York City, Ellington left his successful career in D.C. and moved to Harlem, ultimately becoming part of the Harlem Renaissance. New dance crazes such as the Charleston emerged in Harlem, as well as African-American musical theater, including Eubie Blake's "Shuffle Along". After the young musicians left the Sweatman Orchestra to strike out on their own, they found an emerging jazz scene that was highly competitive with difficult inroad. They hustled pool by day and played whatever gigs they could find. The young band met stride pianist Willie "The Lion" Smith, who introduced them to the scene and gave them some money. They played at rent-house parties for income. After a few months, the young musicians returned to Washington, D.C., feeling discouraged.
