What is "west coast sound"

Dweller rightly describes the San Francisco sound. More in general though, West coast - loose and relaxed. East Coast - uptight and controlled.

In music, West Coast is the sound Fleetwood Mac makes when it hires Stevie Nicks. Singer Nicolette Larsen is another good example.

The let's-all-get-along West Coast sound features a jingle-jangle (The Byrds) that the bitter East Coast sound (Lou Reed, Bruce Springsteen) lacks. Put another way, in West Coast the guitar chords sound on both the up and down strokes instead of chopped out with all down strokes.

Speaker Type, West Coast: Bass Reflex; East Coast: Acoustic Suspension.

AR was not only New England, but Boston, and they operated a demo studio (not a sales room) in Harvard square. Formal atire, optional.

Isn't HiFi Choice a Brit mag? Maybe the reviewer meant Wales or even Ireland.

Also, when I think of West Coast (jazz), I think of Chet Baker.
