Just an idea!!!

[Powerslave]

I haven't been able to even attempt an answer at any of the "link this band to this other guy" type questions, but I was able to come up with an interesting connection after a little research. Note: this will not be a totally prog chain--you will need to venture into other genres to get the answer.

Link: Genesis to Chuck Berry

Genesis

Good Luck!
