One of my first concerts was a free Avril Lavigne show at a mall parking lot in Seattle. Although I don't remember many details, I do remember that she played an unplugged set which I felt wasn't very "punk" of her (she's since self-identified as a "rock chick.") Now that I'm older and a little bit wiser, I would do almost anything to see a young Avril perform "I'm with You" and "Things I'll Never Say" on an acoustic guitar again. Luckily, she's heading out on a Greatest Hits tour this month to awaken the tie-wearing tween that lives inside all of us. Need even more nostalgia?
