On “Hello Kitty” kids guitars. We now live in a world of “challenges.” Not the normal how do I feed my family or how do I keep them safe,but rather Ice Bucket and to a very much stupider degree The Tide Pode challenge…member that one kiddies?! Well, we have a much more entertaining(and safe) challenge upon us. The Hello Kitty Guitar Challenge. Mark Tremonti(formerly of Creed fame,Alter Bridge and, now in his own self-titled band) and Eric Friedman have taken up the Hello Kitty guitar challenge, choosing to embark on a full cover of Metallica’s “Welcome Home (Sanitarium)” on the instruments. Check out the rocking challenge below and lets see what your nieces and nephews can rock on their Hello Kitty guitars!
