What is the difference between east and west coast swing?

The revival of the East Coast hip hop scene as a reemerging identity soon spawned an inter-coastal confrontation. West Coast rapper Tupac Shakur was shot outside of a recording studio in New York in late 1994, an event he would later claim was orchestrated by The Notorious B.I.G. and Puff Daddy. Tupac proceeded to sign with Death Row Records, and the personal rivalry would grow into both a feud between the Bad Boy and Death Row labels. Due to Biggie and Tupac's prominence on their respective coasts, the rivalry is often referred to as the East Coast/West Coast feud. It would culminate into the murders of both rappers in the mid-1990s. In the wake of the deaths of both artists, Biggie's certified-diamond double album, Life After Death, became a huge posthumous success in 1997. Whereas West Coast dominance soon crumbled after the death of Tupac, as Dr. Dre and Snoop Dogg left Death Row Records and Suge Knight was jailed over illegal business practices.
