Prince, Shania, Celine also successes in 2004.

Madonna's blockbuster Re-Invention tour took all of the drama out of the top tour of the year race, ringing up a year's best $125 million in total box office gross by the time it wrapped in September. According to Billboard Boxscore, Madonna sold out 55 of 56 performances worldwide, with an average nightly take of $2.23 million.

"My Re-Invention tour was by far the most creatively satisfying experience I have ever had," Madonna tells Billboard. "I was able to put everything I love into one entertaining event: film, music and dance." The tour was produced worldwide by Clear Channel Entertainment.

Prince's Musicology tour, produced by AEG Live, drew nearly 1.5 million people, more than any other artist, and grossed $90.2 million, second only to Madonna.

Shania Twain was third, reporting grosses totaling $62.5 million and playing to nearly 950,000 fans. The rest of the top 10 are as follows: Simon & Garfunkel ($59 million), Metallica ($53.8 million), Bette Midler ($53.3 million), Sting ($52.4 million), Kenny Chesney ($49.3 million), David Bowie ($46 million) and Toby Keith ($44.3 million).

This year Celine Dion reported more than $77 million from her residency at the Colosseum at Caesars Palace in Las Vegas. If Dion's numbers reflected a "tour" per se, she would rank third among all acts. The Red Hot Chili Peppers, with James Brown and Chicks On Speed, headlined the top engagement at the year, three nights at London's Hyde Park which grossed $17,187,324 and drew more than 258,000 June 19, 20 and 25.

For the fifth consecutive year, Madison Square Garden in New York City tops the list of arenas, reporting music-event grosses totaling just under $73 million. For the second consecutive year, Tweeter Center in Mansfield, Mass., is the top amphitheater, reporting more than $23 million from 32 concerts.
