You guys have got to see this........It is so unbelievable! Joe Gutierrez is sooo dedicated and plays the drums so much that he actually got a BLISTER on his thumb!!!
Most people are grossed out by it, but I think it is cool...bahahahha!
And he also has this hard-as-a-rock callous on his hand.
So next time you think you have practiced enough, think again! If you don't have a blister yet, you need to go back and play some more!
