"Diana Jean Krall", OC, OBC (born November 16, 1964) is a popular Canadian Jazz pianist and singer.
Krall was born into a musical family in Nanaimo, British Columbia, Canada. She began learning the piano at age four. During her youth the family moved to Vancouver. In high school, she started playing in a small jazz group. At the age of fifteen, she started playing regularly in several Nanaimo restaurants.
At age seventeen, she won a scholarship from the Vancouver International Jazz Festival to study at the Berklee College of Music in Boston. She completed three terms.
In Nanaimo, her playing attracted the attention of legendary bass player, Ray Brown (co-incidentally the ex-husband of the late Ella Fitzgerald.) After hearing her play, he persuaded Krall to move to Los Angeles, California, and study with pianist Jimmy Rowles, with whom she began to sing. This also brought her into contact with influential teachers and producers. In 1990, Krall relocated to New York.
Diana Krall and British musician Elvis Costello married in December 2003. They are expecting their first child in December 2006.
