That's probably true...
You can hear a Stones song and can tell almost straight away it's the Stones.
It's a sound that's endured over decades.
The Beatles went through such a range of different sounds in the short time (less than ten years) that where together that where they finished up was 'chalk and cheese' to where they started.

The period of time when the Beatles decided to move away from mop top teen sensations, to serious musicians determined to push themselves to the limit, is the most spectacular transformation in pop music history. They were influenced by Bob Dylan's super trilogy of mid 60's recordings. U2 and Radiohead have followed suit and also went through a transformation in their careers.
