"AC/DC, Y&T, Scorpions...
Didn't have to think too long about that ..."
I'll give you six more: Status Quo, Ted Nugent, Slade, New York Dolls, The Alice Cooper Group and Mott the Hoople, but you'll be able to name vastly more without one I think: Nazareth, Sabbath, Zeppelin, Bad Company (Rodgers only played a little rhythm guitar and it was never prominent), Uriah Heep, Triumph, James Gang, Max Webster, Thin Lizzy (two lead guitarists), UFO (Raymond only played rhythm occasionally), Budgie, Rush, Purple, Rory Gallagher/Taste, Ten Years After, Grand Funk Railroad, Mountain, all those Southern Rock bands (generally two lead guitars or more), Judas Priest (two lead guitars), Golden Earring, Heavy Metal Kids, even CCR in their final incarnation after Tom Fogerty had jumped the Proud Mary. It had of course to do with the fact that in the seventies many bands patterned themselves either after Cream as a power trio or had a keyboarder. For largely economic reasons, keyboard players went out of style with most punk bands.
And AC/DC were initially (incorrectly though) hailed as an Australian punk band in Germany. They first gigged Germany at the height of the punk frenzy. And in early Scorpions, Rudolf's rhythm playing was much less prominent and he played more a secondary lead guitar (they still had a keyboarder back then too). That changed when Uli Roth joined the band (and the keyboard player left) who was less a rhythm player than Michael Schenker (who never forgets his rhythm role though he is a lead guitarist) and largely played fills (when he was not soloing) during his Scorpions tenure. With Roth (a Hendrix disciple not really into the school of chugging rhythm guitar) playing less rhythm, Rudolf naturally played more. That is true to this day, you very often see Rudolf playing the full chords (or power chords) while Jabs is either soloing or just hitting the lower E string.
