Wynonna Judd [ tickets ]'s summer tour schedule is packed with her typical mix of fairs and festivals, including a July 4 concert with her mother, Naomi, to celebrate The Judds [ tickets ]' 20th anniversary.

The Judds will appear at Houston's Freedom Over Texas 2004 celebration, which takes place at Eleanor Tinsley Park. The event will be broadcast throughout Texas, and will also feature three other stages of music and a fireworks show.

Wynonna continues to support her 2003 album, "What the World Needs Now is Love" which debuted at No. 1 on Billboard's Country Albums chart, and at No. 8 on the Billboard 200 album chart. The set marked her first No. 1 debut since 1993's "Tell Me Why."

Among the tracks featured on "What the World Needs Now is Love" are "Flies on the Butter (You Can't Go Home Again)," a duet that pairs Wynonna with her mother; a cover version of Elvis Presley's "Burnin' Love," which first appeared on last year's "Lilo & Stitch" soundtrack; and a cover of Foreigner's "I Want to Know What Love Is," which features a guest appearance from guitarist Jeff Beck.

The Judds have been mostly dormant in recent years, but Wynonna and Naomi occasionally reunite for special occasions. The duo has sold more than 20 million albums, scored 14 No. 1 country singles and won five Grammys, according to a press release.
