A prominent counterpart of soft rock in the late 1970s and early 1980s came to be known as yacht rock; its name coined in 2005 by the makers of the online video series "Yacht Rock". Originating from California's session musicians, yacht rock only partially overlapped with soft rock; it could include soft to mid-level (but rarely ever purely hard) rock. Much of the "West Coast sound" of yacht rock bore similarity to some of the East Coast soft rockers of the era such as Rupert Holmes and Hall & Oates, leading to the conflation.
