Not many RATM fans on this site, it appears. If you were taking a sneaky poll on average age group of CSers, I think you got your answer.
Yes, RATM are an awsome band. My 18 yr old son is as exited as you about them coming out. I tipped him onto them about 6-7 yrs ago (part of my contribution to his musical education).
I was around as a kid (a very young kid, thank you) to catch the end of the golden age of rock (mid 60s to early 70s). Then the late 70s and 80s was a very lean period. Thankfully, the early 90s renewed my faith, with an explosion of great bands and music (eg. Pearl Jam, Nirvana, Smashing Pumpkins, Chilli Peppers, Tool, Radiohead and, of course, RATM, etc). We get pumped up when Tool and PJ come out, but this is something different as RATM have not really been before (and we thought never would).
So, hope you get to see them (they will probably turn up at the BDOs) and enjoy.
By the way, making any good coffee? (Thought Id add that as this IS Coffee Snobs.) :)
