Lady Gagup shouldn't be in such company--she barely qualifies as performance art. Take away her increasingly ludicrous costumes, dancers, and Broadway staging, and you're left with we-gotta-get-something-on-the-radio tripe with shock-for-shock's sake lyrics. As soon as she pushes the envelope so far she hits the wall, she'll be traded in for a younger model--just like her mother Britney and her grandmother Madonna.
