[3] In February 1971, Haslam became the new lead singer of Renaissance after answering an advertisement in the British periodical Melody Maker and auditioning for the band in Surrey.

[4] Charles Snider stated: "Annie Haslam's voice, soaring high along with the melody, is the big news.

In 1977, Haslam began her solo career with her album Annie in Wonderland, produced by Roy Wood, who played most of the musical instruments and duetted with her on one track.

Haslam released an EP called Night and Day, her first solo recording for some years, with Welsh rock band Magenta in 2006.
