From the Elephant 6 group (maybe that should be a Rock and Roll HOF induction), of Montreal could be the best project yet. Led by Kevin Barnes, the material of this band covers a wide range of emotions and experimental sounds without going too far in the land of quirkiness. This is one of those bands that has the potential to be viewed upon very highly over time.

O.A.R. (Of a Revolution) has slowly been making head way in the Alternative Rock world. Every album they did, slowly built on the success they had before. This being said, the band has a lot of building still left to do if they want to be considered a Hall of Fame type outfit.  

Nightwish may not have been the best Symphonic Metal band but they may make a claim as one of the best. Their music had an eerie beauty to it, and listening to their music you feel like you are listening to a symphony; despite the electric guitars. With that said, the band may have had multiple number ones in Finland but without even a top 100 in the States, they are largely anonymous in North America. 

One of the best pure blends of Pop and Punk going, New Found Glory may not have had the highest level of commercial success, but of the newer wave of Punk influenced bands, they were among the most melodic. Odds are that this will not equate into a Hall of Fame induction but it will be an overall solid career, which is better than most bands ever get.
