i can do everything on expert except the pro keys, pro bass, or pro guitar. my wife and i do vocal harmonies and have quite a few top 20 rankings. i have over 800 dlc and 54 pro upgrades so far as of today. i mainly play bass while my wife sings but will do guitar if needed but don't expect gold everytime if that's the case. i can do some pro drums on expert but mainly on hard or regular drums on expert. add me to jam, just say it's for rock band iin the invite.
