Lady Gaga is still outselling her competition, at least according to TicketNews’s weekly top events for the week ending April 18.

The singer is the top selling artist overall with a 6.25 power score. Wicked trails behind her with a 3.95 power score.

Roger Waters announced recently that he’ll be touring North America to play, cover-to-cover, Pink Floyd’s classic “The Wall.” The 35-date tour begins September 15, and already Waters is number three in these rankings with a 3.94 power score. He beats out Justin Bieber, who is number four (3.62).

Aerosmith & The J. Geils Band will play at Fenway Park on August 14; tickets sales for that event place the duo at number six (2.27), behind the park’s own Boston Red Sox (five, 2.39). Red Sox rivals the New York Yankees are number seven (2.16).

Rush will bring its “Moving Pictures” tour to North American venues this summer and now the band is at number eight (1.86). Rounding out the overall top ten are Bon Jovi (nine, 1.54) and Tim McGraw & Lady Antebellum (ten, 1.45).

Lady Gaga (11.12), Roger Waters (7.01), and Justin Bieber (6.43) preside over the Top Concert Event rankings. Other top selling acts include The Eagles (seven, 2.56), Taylor Swift (eight, 2.31), and James Taylor & Carole King (ten, 2.01).

The Boston Red Sox are number one in the sports rankings with an 8.33 power score. Following are the Yankees (7.18) and the Minnesota Twins (3.81). The Mexico soccer team is still selling tickets, enough to give the team the number four spot and a 3.73 power score. Two other baseball teams making the top ten are the Chicago Cubs (five, 3.28) and the Philadelphia Phillies (six, 3.23)

With NBA Playoffs underway, it’s no surprise that those games make the top ten. The Western Conference Quarterfinals featuring the Denver Nuggets is number seven (2.54) and the Western Conference Quarterfinals with the Oklahoma City Thunder is number eight (2.50). At number nine is UFC 115 (2.50) in Vancouver, and at number ten (1.97) is the WWE.

“Wicked” (31.21), Jersey Boys (8.44), and Billy Elliot (8.17) sit atop the theater rankings; Lion King is number four (5.08). Chicago: The Musical is still a popular show, as it comes in at number nine (2.24). A Little Night Music is number ten (1.98).

Behind “Wicked” (27.02) and “Jersey Boys” (13.22) in the Broadway rankings is The Addams Family (7.84). Fences stays at number six (5.30) and is followed by classics The Phantom of the Opera (eight, 2.44) and Mamma Mia! (nine, 2.07). Closing out the Broadway top ten is Green Day’s American Idiot (ten, 1.84).

Cher still has the top selling show in Vegas (69.70). Cirque du Soleil – The Beatles: LOVE follows her in number two with a 9.35 power score. Barry Manilow breaks into the Vegas top ten at number three (6.17), outselling Vegas staples like Blue Man Group (four, 5.43) and Cirque du Soleil – KÀ.

Le Rêve is number six (1.51) and Jay Leno is number seven (1.40). Criss Angel: Believe makes the Vegas top ten again after a brief hiatus; he’s number nine (0.96). Rita Rudner has the tenth best-selling Vegas show and a 0.91 power score.

TicketNews Exclusive Rankings and Power Scores are based on ticket sales from the TicketNetwork Exchange™, the world’s largest secondary market exchange. A Power Score illustrates a given event’s category-specific significance. Two factors are used to calculate a power score: total ticket sales from the given event and total ticket sales within the category. As such, power scores should only be used to compare events within a particular category.
