Both were excellent versions of "Nica's Dream"; the West Coast version kind of flowed and oozed, while the East Coast was "hard riding"; imagine an outlaw making his get away from the posse across the badlands, you could hear Horace Silver riding hard on those keys, while Carl Perkins was laid back and cool.
The East Coast was hot and explosive, full of emotion; Junior Cook, on tenor, and Blue Mitchell on trumpet were lightening quick, and jazzy to the extreme; which is what East Coast is all about, I started sweating just listening to it.
If you have a temperature, and want to cool off, you need West Coast, but if you want to get hot and excited, it's East Coast.
