Just so we're all on the same side of the disc here....there was DynaGroove,
there was DynaFlex (aka taco shell pressings), and there was something called
DynaRange that escapes me at the moment. (There was also DynaShore but she
hadn't recorded for RCA for quite a while by that time.) DynaGroove was
Vicspeak for overmodulated and distorted. The raised ridge and center was
called "Gruve Gard" but most North American LPs began to have those in the mid
50s, except Decca.
