I've had a think about this. My biggest influence is John Entwistle, without a doubt. He's the reason I started playing, and the reason I had wanted to play since the age of 8 after seeing this clip:
Of course the camera completely ignores John throughout, but his playing and tone is just shattering, particularly for the era. A howling, distorted grind. He absolutely dominates here.
It's easy to forget just what a gamechanger John Entwistle was - this clip shows why he was.
