I was a GH fan before i bought rock band 2 which i love! sadly i don't have plenty of dlc but i garantee that i'm really good on guitar, drum and bass. I play on expert on these instruments and have 5 gold starred songs like ride the lightning, and justice for all, lucretia and i can go on!
ADD ME : Crimson194 In the future i will buy more dlcs
