a silly little question

[Rick and Roll]

Since the last Quiz de Force by Mr. Dinosaur, we haven't had even a whiff of a quiz.

I think I may have scored highest, so I'll throw a question in.

On the May 8 Rickter Scale, I'll be doing an entire show on a band that is a prog icon.

The guitarist from this band has the same initials as the band.

Another clue or two available, but I doubt you may need them.

Please name the band and the guitarist.
