So I got Rock Band for Christmas (along with every downloadable song so far so I have 82 songs right now haha) and on the first day of playing, down strumming on my guitar died. So while I wait for my replacement, I decided to still try and beat Expert Guitar Solo tour.
And yeah, I ended up 5 starring Green Grass and High Tides Expert (the last song on guitar solo tour) with only up strumming and the solo frets (which are the best addition to the game ever).
I thought that was pretty cool.
