On a slightly related note of impressing guitarists in other genres and slightly straying off topic, Benjamin Verdery related an anecdote on a podcast where he was asked to recommend and supply a classical guitar to the Rolling Stones’ Keith Richards.
When he was about to meet him and whilst he was waiting, Benjamin was playing some Bach on it just as Keith came in and Keith said ‘Ok, stop showing off then!’
In the podcast, Benjamin was talking about Keith playing an old blues tune on the guitar and then they talked about how awkward Chuck Berry was to work with (there is a documentary where Chuck Berry and Keith worked together but Chuck didn’t take likely to people touching his amp, to put it mildly).
He didn’t emphasise that Keith was really impressed but I got the impression that he would have been from Benjamin’s classical playing
