If you like dance and pop, the music is great — well-produced and delightfully contagious. But the spectacle that is Lady Gaga is not really about the music, even though she did win two Grammys this year. It's not even about the outfits, including the crazy glam-rock bodices and odd headgear. Rather, Stefani Joanne Germanotta has become famous by being obsessed with fame (her two albums are called The Fame and The Fame Monster). It's performance art, and at least for now, everyone is loving the performance.
