But they were both British, and both influenced it. In fact, Black Sabbath was still making music during the wave (coincidentally enough, right around when Dio became the vocalist, for Heaven and Hell and Mob Rules).
Yo, since we're splitting hairs, how come earlier you said Judas Priest wasn't part of the wave? They didn't start making Metal till the mid to late seventies, which is when the wave started, and didn't become massive till the eighties, when the wave hit it's peak. They're well known as being the head of the NWOBHM.
