Technically it was some Orchestra when I was young.
Then as for mainstream artists: Brooks n' Dunn shortly before 9/11 or STYX at some local Corn Festival, but I'm not claiming them as my first true concerts, because I hated being at each of them with a passion.
Other then that, It's my goal this and next year to go to my first actual mainstream rock concert.
First concert that I paid my own ticket for and really chose to go to was Christina and Justin's Justified and Stripped tour. But I was dragged by sisters to go to the New Kids On The Block concert when I was like 5 or somethin.
i went to a radio station one and the performers were J-Kwon, Amanda Perez, Mase, Ying Yang Twins, JoJo... and that's all i can remember, i know there were more.
I'm gonna shoot myself for saying this, but I was at the Indian Seafood Festival here and the first celebrity I had ever heard live was Gretchen Wilson. = X Other than that, I have seen The All-American Rejects and Daddy Yankee here in PCB. = )
