In November 2000,[5] Ken Krongard, an A&R representative, invited Antonio "L.A." Reid, then-head of Arista Records, to producer Peter Zizzo's Manhattan studio to hear Lavigne sing. Her 15-minute audition "so impressed" Reid, he immediately signed her to Arista with a deal worth $1.25 million for two albums and an extra $900,000 for a publishing advance.[6][1] 由 this time, Lavigne had found that she fit in naturally with her hometown high school's skater clique, an image that carried through to her first album, but although she enjoyed skateboarding, school left her feeling insecure. Armed with a record deal, she dropped out to focus on her 音乐 career,[5] but she still had to inform her parents of her decision. "I wasn't going to turn [the record deal] down. It's been my dream all my life. They knew how much I wanted this and how much I've put into it."[16][8]
Lavigne released her debut album, Let Go, on 4 June 2002 in the U.S., where it reached No. 2 on the Billboard 200. It peaked at No. 1 on the Australian, Canadian and United Kingdom charts. This made Lavigne, at 17 years old, the youngest female soloist to have a No. 1 album in the UK until that time.[17] 由 the end of 2002, the album was certified four-times platinum 由 the RIAA, making her the bestselling female artist of 2002 and Let Go the top-selling debut of the year.[18] 由 May 2003, Let Go had accumulated over 1,000,000 sales in Canada, receiving a diamond certification from the Canadian Recording Industry Association.[19] As of 2009, the album has sold over 16 million units worldwide,[20] and the RIAA has certified the album six-times platinum, denoting shipments of over six million units in the U.S.[21]
“    I don't get overwhelmed, just because I feel like I've kind of prepared myself for it. All my life this is what I've wanted, what I've dreamed about, and I knew this would happen. I've been 唱歌 ever since I was really young and I've wanted this so bad, and I told myself I would do it.    ”
