West Coast Swing is another offshoot of the Lindyhop/Jitterbug dances that was developed in the Los Angeles area in the 1950’s. It is a slotted dance in that it is performed in an imaginary slot in the dance floor where the follow progresses back and forth ‘through’ the lead who moves a minimum amount to clear the path. There are many theories about why the slot was invented including Hollywood’s need to have the dances be in a line so a camera could roll back and forth in the filming of them.
