Maybe the coolest family in rock music? (if not, feel free to suggest others!)

Watcha!

There's very likely some better options as for greatest family in rock music.
You'll probably know some yourself - feel free to recommend here.

I quite like the sweet Japanese Soma family from Hokkaido: dad and mum in their 30s, Yoyoka aged 11 on the drums, 8 year old Shido frontman.
They like Nirvana (and other rock acts) a lot:







Admittedly, Shido currently lacks a fair bit as a vocalist atm, but he's only 8, he's singing in a foreign language, he's got the attitude and he sounds like a demon!
Give him 4 years and he'll be doing alright.

3 very decent instrumentalists backing him up, too.
Here's a bonus video here of 11 year old Yoyoka whacking out Burn by Deep Purple:


Anyway, if you know any other half-decent family groups ripping it up on the interwebz, feel free to chime in here.

Cheers,
