Baltimore Club music began at places like Club Fantasy, the Parados, Hammer Jacks, Odell's and Club Choices.
According to Todd Inoue of the Washington Post, the Baltimore Club sound is "an up-tempo hybrid of hip-hop and house with kickdrums, chants, handclaps and bizarre synth effects set to accelerated tempos."
Comparable to house music, the Baltimore Club sound also contains R&B, rap, hip hop, crunk, 80s synth, techno and rock influences.
Sampling tracks include George Bush stuttering through a speech and such popular television show samples as Spongebob Squarepants and Sanford and Son.
Expanding north, the Baltimore Club sound reached New Jersey, developing a cult following in places like the Brick City club.
Discovering the sound through the release of the 12-inch remix of Gwen Stefani's "Hollaback Girl," major labels are now taking notice.
