Lady Gaga’s wildly successful Monster Ball blew the roof off four sold out Radio City Music Hall shows earlier this year. Because her massive NYC fan base was not appeased, The Ball returns tonight to Madison Square Garden where Lady Gaga and opening act Semi Precious Weapons will dazzle with their unique spectacle of a tour. Gaga is as famous as she can get right now and her constant media attention and ability to reinvent herself with every appearance ensure she will not only sell out this week’s shows, but the two she has added in February. Semi Precious Weapons are not the cultural phenomenon that Lady Gaga is (yet), but they compliment her well with groundbreaking, outrageous live performances and a loyal NYC fan base. Think of them like Queen on acid. The Monster Ball will be held at MSG tonight, 7/7, 7/9, 2/21/11, and 2/22/11. Get your tickets fast- there’s no stopping this party.
