I'm a bit of a fan of understatement. You're emulating quite a gregarious era - one populated by bands who wouldn't hesitate for a second in telling you who they are and in what way they're the most important and ferocious band in the world.
So I'd be tempted to go for something that sounds like a rock band, but a timid one. Either by being quite polite and deferent - "Sensible Volume," or some such - or by choosing a name that sounds like you were aiming for something truly ferocious, but couldn't think of anything. "Steppenmother" is making me giggle - combination of Steppenwolf, which is German for coyote and a rock band of the right era, and stepmother, which isn't.
Actually, if you don't take Steppenmother, I'm going to save it for myself.
