Hendrix was ground breaking, one could even say he changed music forever.
One hit wonders, people only have ever heard one song from that band.
Most people can recognize Purple Haze, Hey Joe, Along the Watch Tower, and Foxy Lady. Some of those songs were covers that widely eclipsed the original artist. Hendrix also popularized new recording methods and the use of the wa-wa pedal.
Not quite sure how you can call Rush a one hit wonder either because they are still around making music. They also have one of the most proficient drummers to ever live.
I was trying to be funny, but make a point too if you reread my posting. One of the other posters noted:
"IMO, one hit wonders don't get in, gold/platinum records show popularity but not necessarily Hall worthiness."
Rush really did have only one "hit" meaning making it into the top 40, same goes for Jimi Hendrix and Janis Joplin. Like the other poster mentioned, real "One Hit Wonders" really don't make it in the RnR HOF, like The Archies (unless you count them as a novelty hit). Same goes for the gold record statement.
Deep Purple might have had gold records, but that does not mean they were any good. A fan of course is going to think they deserve to get in and I get that. But in reality, is Deep Purple really deserving to get in? Probably not. They are just a standard generic sounding rock band from the 70's that got overplayed like Boston and Foreigner. But again, that is my option and I get why people might want to disagree.
I like Yes, and I think they have alot of redeeming qualities. But are they in the same league as other progressive rock bands like Rush or Dream Theater, maybe/maybe not. But I really don't think compared to other bands on the list they will get it. But who knows.
