Anyway, In response to your previously asked question via XBL; yes. I have watched a few videos on youtube of how to set up the grid and have gotten close a few times. I got 5 black pearls once and hope to someday finish it.
I just finished up the last Band World Tour achievement in Rock Band (Big in Berlin) and am quite ecstatic about that. Now, onto the five stupid singing ones!
Congrats again on Seriously!!
Oh, and how long did it take you to do the Annual Vidmaster Challenge?
