Full story from his sister's Facebook post:
"so today is my little brothers 16th birthday, and his first birthday without our dad. But, as dad was always filled with surprises.About a month ago I dropped J off at his guitar lesson, and one of the amazing instroctors told me there was something i should see. When he showed me i just dropped to my knees. I just couldnt believe it. But i had to keep it a secret until his birthday.
So this morning i woke up and picked up my brother from school and blindfolded him. Drove him to the music center and this is the outcome. A big thank you goes out to the music center, who helped keep my dads dream alive."
