Red Rocks is a fantastic place for concerts. I used to live right over the hogback from Red Rocks. (just outside of Morrison) I saw quite a few excellent shows there. Bonamassa would be a real treat. I hope you get to see him there.
It really is a great place. I've been to a few concerts in my life, and that is my favorite place. Saw Mark Knopfler there twice - we used to live in Aurora.
Bonamassa is a monster, for certain. When he was young, he was a child prodigy. He has gotten so much better and he seems to have his head on straight. He is a historian of the instrument and the masters of the past.
