Not sure if this is the same, but Derek Brimstone is a banjo player.
An excerpt from his website
The huge entertainment factor of his shows often causes the audience to overlook the fact that Derek is also a superb and highly respected guitarist with, as Melody Maker once put it, "one of the most precise claw-picking techniques in the business". He is also highly regarded as a clawhammer banjo player, and has published excellent and successful tutors for both instruments.
