Phair's third album, "Whitechocolatespaceegg", was released in 1998 after some delays, which included a disagreement about content; at one point, Matador rejected the album as submitted, and asked Phair to write a few additional radio-friendly songs for the set. The album displayed a more mature Phair, and reflected some of the ways marriage and motherhood affected her. While the single "Polyester Bride" received some airplay, and the album received many positive reviews, it was no more successful commercially than her previous records. To promote the record, Phair joined Lilith Fair. Phair performed on the main stage along with acts like Sarah McLachlan, Emmylou Harris, Sheryl Crow and Missy Elliott. She also opened for Alanis Morissette on the latter’s 1999 Junkie Tour.
