Frogman, what you called "Cool School", we called "West Coast". When I bought records every week, I always bought half West Coast. Since that time "All" of those original records have gone with the wind, but I've been able to replace the other records, which might be on the 5th copy by now, while the "West Coast" records were no longer available.
In the case of East Coast, West Coast, don't get locked down to geographical area; while Lennie Tristano's studio was in New York, the music was strictly "West Coast".
