The singer kicks off the festivities at New York City's Madison Square Garden June 21, and will wind down with a four-night residency at the Encore Theater in Las Vegas. The concert, created to back up the star's hit album I Am…Sasha Fierce, features an all-female band and a hefty, 71-costume wardrobe designed by Thierry Mugler.
Fans can also expect some funky masks and unlikely covers (Sarah McLachlan, anyone?). Tickets go on sale to the general public April 25 (and April 20 for fan club members). Additionally, at every venue but Vegas, the fiercely sweet star is making 2,000 seats available for a recession-friendly $20.
