Let me tell you a story.
Once upon a time there was a guy named Samson, or Sam, for short. He was really tough but his strength wasn't attributed to his muscles, but his hair. One day this girl that he liked asked him why he was so strong and after the little lies that we tell the people who we like, he came out with the truth. After she found out, the wench cut it all off! When he woke up Sam found out that his strength was gone and he was a wimp just like everyone else. When everyone found out that he lost his strength, they poked out his eyes and then made fun of him every night until his hair had grown back, and guess what. With the re-growth of his hair, his strength came back and he used it to collapse the building he was in, killing himself and all the people who were picking on him. Tragic eh?
Now let me tell you another story.
A couple of weekends ago, I was in Edmonton with my family and they conned me into getting my haircut. They presented good reasons why I should have one; my hair was getting a little long, my sister has a wedding in a couple of weeks and she wanted me to look presentable, you know, the list that the relatives make up... So I put some conditions that I thought were impossible on a haircut and to my surprise, my family filled all of the conditions, so my hair was cut. I remember sitting in the chair, tears flowing from my face thinking
"How can I rock with short hair?
I play guitar in part so that I can swing my hair around.
My Rock Strength will be Gone!
Just like Sam!
They are going to poke out my eyes and make fun of me!"
Yes, I was a sorry sight. Sitting in the middle of the mounds of what used to be my long beautiful golden locks, shivering in the cold, until I went outside that is, then I promptly sun burned my neck and ears. After I returned home, I picked up the guitar to see if all of my chops were gone, but to my delight, they were still there! My guitar stills were still intact and I was elated! Upon further contemplation on this matter I realized that there was really no need to ever be alarmed. After all there are pleanty of great rock musicians who have (or have had) short hair and still rock! For Example:
Synister Gates - Now Despite the cheese of Avenged Seven Fold, this guy knows how to play guitar. It can't be denied.
Matt Heafy - Same story, say what you will about Trivium, Matt is a great guitarist - Even with his short hair.
Rob Halford - Now he doesn't play guitar but This guy has been Rocking with No Hair at all for a LONG time!
Kerry King - Same Story as Rob
Joe Satriani - He had long hair but as it started to thin, off it went... ALL of it! Even after that, he was (and is) still amazing
Steve Vai and John Petrucci both have had points in their careers when they had short hair and did they suck then? No. They didn't. Ever.
These aren't the only ones either! You can still rock even if you have short hair. And that is that. (Sorry about your bad luck Sam)
