200. Rory Gallagher
As this list is peppered with acclaimed guitarists, there can be an argument made that few were on the level of Rory Gallagher. The Irishman was an avid student of the American Blues and was able to take that style of music to dimensions not previously looked at. Gallagher did not really try to penetrate the American market, but he was a legend in Europe and the amount of British musicians who were influenced by his soulful guitar playing is a large one.
