With Destiny’s Child calling it quits, group member Kelly Rowland has quickly dived in to work on her next solo LP. Among the collaborators on the as-yet-untitled Columbia set are songwriter Sean Garrett and Solange Knowles, the younger sister of Beyonce Knowles. “It has been a very personal album for me,” Rowland tells Billboard.com. “It has been one of the best experiences of my life. It’s a look into the past two years, going through different relationships, love and growing as a woman. It’s a soul-searching record. It’s really beautiful.” Rowland’s ex-group mates will not be far from her thoughts as the creative process rolls forward. “Michelle (Williams) is in the studio right now writing a song for my album,” she enthuses. “And I’m going to play all the songs for Beyonce and see which ones are her favorites. I always look to her for advice.” The upcoming album is the follow-up to Rowland’s 2002 solo debut, “Simply Deep,” which debuted at No. 12 on The Billboard 200
