What is 'drive'?

Thanks to Mel Corry for this link to a YouTube video of Sammy Shelor (photo, left; four times IBMA Banjo Performer of the Year) at a workshop, explaining exactly what is meant by 'drive' in one's playing. Mel says: 'I have been trying to put in words my own thoughts on this for years and Sammy explains it all in a couple of sentences.'

 In the video, Sammy Shelor also quotes fellow banjoist Terry Baucom, the 'Duke of Drive', as saying: 'Drive is a state of mind'. Find out more here.
