Like Weather Report, The Mahavishnu Orchestra was a key cog in the development of Jazz Rock fusion. Leaning more towards Rock elements than Weather Report did, The Orchestra was able to cross mainstream lines a little better and actually put out an extensive catalogue considering they were not around for very long. They are certifiable long shots for the Hall, but stranger things have happened.
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.
With Paul Rodgers already on this list for fronting Bad Company, it is a possibility that he could have a better chance to get into the Hall with his previous band, Free. As part of the Blues based Rock that came out of Britain, Free was among the grittiest and in their brief time together put out some of the more underrated work of the genre. With a major hit (All Right Now) that remains a Classic Rock staple, they may find their way on the Hall’s radar one day.
If you ask the average person which Beatle’s solo work is not currently recognized in the Rock and Roll Hall of Fame, most would correctly predict Ringo Starr. If you ask that same person who had the least amount of solo hits of the Beatles they would incorrectly pick Starr, who had the exact same amount of top ten hits as John Lennon and George Harrison combined. Starr’s solo work was poppish and quirky and despite his solo success is actually very much forgotten. As a Beatle he has a shot but until the most disrespected member of the most respected band gets more credit, Ringo Starr could likely remain the only Beatle with only one induction.
