Alanis Nadine Morissette; born June 1, 1974) is a Canadian-American alternative rock singer, songwriter, musician, multi-instrumentalist, record producer, and actress. Known for her powerful and emotive mezzo-soprano voice, Morissette began her career in Canada in the early 1990s with two mildly successful dance-pop albums. Afterwards, she moved to Holmby Hills, Los Angeles and in 1995 released Jagged Little Pill, a more rock-oriented album which sold more than 33 million copies globally and is her most critically acclaimed work. Her follow-up album, Supposed Former Infatuation Junkie, was released in 1998.

Morissette assumed creative control and producing duties for her subsequent studio albums, including Under Rug Swept (2002), So-Called Chaos (2004), and Flavors of Entanglement (2008). Her eighth studio album and most recent to date, Havoc and Bright Lights, was released in 2012. Morissette has sold more than 75 million records worldwide and has been dubbed the "Queen of Alt-Rock Angst" by Rolling Stone.
