To all who received a free lesson card from Rock House at the Mayhem Fest... Bad News and Good News. the bad news, I messed up and forget to add the code into our system son until Monday July 27 at around 11 a.m. the MH codes will not work. The GOOD NEWS though, you can use code FX123789 and that will work for sure. Sorry again everyone, we're only human. I hope you enjoy the free lessons so much that you tell all your friends to go out and buy Rock House DVDs so that we can hire someone to make sure this doesn'y happen again.
