Did Larry Graham really give us first what is refered to as slapping(Thumping&Plucking) or was he the first to become worldly reconised for it because he was heard on a recording utilising it before Louis Johnson.therefore garnering that title and isn't it possible these two talented Bassist could have simply been working on it during the same period of their conceptional developement and never even thinking anyone else was doing it(in a modern format)and this not at all an attempt to take anything away from these two talented influences on Electric Bass.
